HOW

IMPORTANT

IS

YOUR

DRIVE

SYSTEM?

The fasteners you use in your product may

seem insignificant, but they are an important factor in your overall productivity, quality and profitability. The drive system on those fasteners affects assembly speed, downtime, worker comfort, and the amount of reworked and/or scrapped components, as well as product design. WHY OTHER DRIVE SYSTEMS CAUSE PROBLEMS ON THE ASSEMBLY LINE HEX
? point contact causes stress risers to develop, which damages driver bit and fastener recess ? 60° drive angle is inefficient in transferring torque
points of contact cause stress risers to develop rounding off of contact points from driving pressure to counteract camout, additional force (end load) must be placed against the driver

60° drive angle

Tool and fastener damage is common

CRUCIFORM
(includes Phillips, ACR? Phillips II and Pozidriv?)

? Camout, which forces the drive tool out of the recess, is common ? Camout and its limits on torque transfer can prevent a fastener from being fully seated ? Excessive end-load, required to prevent camout, can reduce bit life and cause worker fatigue or injury ? Camout and tool/recess wear can create debris in an application

driving force is carried up sloped sides, forcing driver up and out of recess (camout)

sides are sloped to align driver bit

proper tool engagement is difficult, limiting the transmission of torque

Concentrated stresses can cause breakage

TORX? DRIVE
? Allows higher torque transmission ? 15° drive angle still permits a small amount of radial stress, which can reduce bit life 15° drive ? Tool may be difficult to align properly in angle high-speed assemblies
tool engagement limited by fallaway straight sides prevent camout Wide tolerances can result in a loose fit between fastener and tool bit

PROBLEMS

Perhaps you have come to accept frequent tool bit changes, camout, damaged components and slowed assembly lines as a cost of using fasteners in your product. But it doesn’t have to be that way. The TORX PLUS? Drive was designed to enhance assembly line performance. Manufacturers all over the world have realized significant improvements and cost savings by switching to the TORX PLUS Drive.

Most Common Fastener Driving Problems*
Camout and tool slippage: 71%

TORX PLUS? Drive SOLUTIONS
The straight, vertical sidewalls of the TORX PLUS Drive System virtually eliminate camout. Also, the TORX PLUS recess completely encloses the driver tip, reducing tool slippage as well as costly and unsightly damage to the fastener and surrounding surfaces. The elliptically-based geometric configuration of the TORX PLUS Drive System maximizes engagement between driver and fastener. It spreads driving forces over the surface area, extending tool life. TORX PLUS Drive is the only drive system designed to ensure optimum torque transmission and, ultimately, required clamp load. With a true 0° drive angle, the TORX PLUS system virtually eliminates the radial forces that can cause stress on fastener recesses. Ergonomic studies demonstrate that the TORX PLUS Drive System can reduce fatigue and muscular stress during the manual assembly of fasteners. That’s because little or no end load is required to keep the driver engaged in the recess.

LONGEST TOOL BIT LIFE AVAILABLE
The ellipitically-based geometry of the TORX PLUS Drive system maximizes lobe engagement between driver and fastener, spreading driving forces over its surface area. This extends tool life and maximizes torque transfer. In test after test, on assembly line after assembly line, the TORX PLUS Drive has been proven to significantly outlast all other drive systems.

TORX PLUS Drive is proven to significantly outlast the competition

REDUCES ASSEMBLY LINE DOWNTIME
One of the most overlooked assembly line costs is downtime. Every time a fastener drive bit fails, the line has to be shut down to change the bit. Over time, line downtime can have a significant negative impact on productivity and profitability. Many customers who have switched to the TORX PLUS Drive are reporting that they have been driving 2 to 10 times more fasteners per bit.

Note: Various drive systems compared with a dedicated automated driving machine. M6 x 1.0, pan head, Class 10 fasteners driven at 330 rpm to 15Nm with 13.3 Newtons end load. All failure modes were bit fracture.

DRIVE BIT COSTS REDUCED BY $15,000 ANNUALLY
APPLICATION: Automotive air suspension system ASSEMBLY METHOD: Automated assembly line utilizing a 4-position, multi-spindle driving station to drive Plastite? fasteners ASSEMBLY PROBLEM: Customer replaced their four Phillips drive bits three to six times per day over three shifts. This resulted in assembly line downtime in addition to the costs of replacing 12 to 24 bits per day. TORX PLUS DRIVE SOLUTION: The first TORX PLUS bits were replaced after four months of use, and then only as a precautionary measure. The customer noted that the bits were hardly worn and could have lasted much longer. CUSTOMER BENEFITS: ? Lowered drive tool costs by $15,000 annually ? Reduced assembly line downtime due to fewer drive bit changes ? Improved productivity

TORX PLUS DRIVE SOLUTIONS

REDUCES ANNUAL DRIVE TOOL COSTS
Although a single TORX PLUS Drive bit or socket may cost more than competing systems, its longer life translates into more assemblies per bit and significantly lower overall tooling costs.

QUALITY

ACHIEVES PROPER CLAMP LOAD
If the proper clamp load isn’t reached, or if camout forces a driver out of the recess before it is fully seated, the fastened joint can easily loosen. This can lead to leaks, squeaks, rattles or even complete joint failure, which may require service in the field and result in higher warranty rates. TORX PLUS Drive is the only drive system designed to ensure optimum torque transmission and, ultimately, required clamp load.

MINIMIZES REWORK
Poor torque transfer due to drive bit wear can result in a poorly built component that needs to be disassembled, reworked, and reassembled, which adds labor as well as material costs. Scrapped rejects – components that cannot be reworked – represent wasted costs. The longer bit life of the TORX PLUS Drive helps ensure that proper torque transmission occurs consistently.

PREVENTS DAMAGE TO APPLICATION
If tool slippage or camout forces the driver out and across a component, damage to the surrounding surfaces, such as scratches and dents, can occur. TORX PLUS Drive recesses completely enclose the driver tip, preventing tool slippage. That design feature, along with minimal camout, means the TORX PLUS Drive bit will stay where it belongs, preventing damage to itself, the fastener recess, and the application. Camout and tool/recess wear can also create damaging debris. This diminishes the aesthetic value of the fastener, and, more importantly, can cause irreparable damage in electronic assemblies, airbags, and other critical applications. The longer life of the TORX PLUS Drive minimizes tool and fastener wear, and its straight sidewalls virtually eliminate camout. That makes the TORX PLUS Drive the optimal drive system for every application.

REDUCES WORKER FATIGUE AND MUSCULAR STRESS
Workers can experience fatigue and muscular stress during the manual assembly of cruciform or slot drive fasteners, caused by the pressure they must exert to keep the driver engaged in the recess (end load) This can lead to reduced productivity or even injuries. Ergonomic studies demonstrate that the TORX PLUS Drive System can reduce fatigue and muscular stress during the manual assembly of fasteners. That’s because little or no end load is required to keep the driver engaged in the recess.

DESIGNED FOR HIGH TORQUE TRANSMISSION
Unlike the inefficient designs of other systems, TORX PLUS Drive is the only drive system designed to ensure optimal torque transmission. With a true 0° drive angle, the TORX PLUS system virtually eliminates the radial forces that can cause stress on fastener recesses. The high torque transfer capabilities of TORX PLUS Drive means it can utilize increased seating torques without increasing current bit usage levels. High torque transfer capabilities are also important during removal of a fastener in service environments, where corrosion can cause seizing in the joint.

APPLICATION: Refrigeration compressors ASSEMBLY METHOD: Automated assembly line

PRODUCTIVITY AND ASSEMBLY QUALITY IMPROVE

ASSEMBLY PROBLEM: An internal hex fastener was causing excessive line stoppage due to the number of drive bit changes – the manufacturer was able to fasten only 8,000 screws per hex bit. Also, a large number of assemblies had to be rejected when the hex bits were unable to reach proper torque levels. TORX PLUS SOLUTION: With the TORX PLUS Drive System the customer was able to fasten over 500,000 TORX PLUS fasteners with a single bit, and the proper torque levels were easily reached. CUSTOMER BENEFITS: ? Lower drive tool costs ? Fewer drive tool changes ? Improved productivity and reduced downtime ? Reduced rejected assemblies ? From 8,000 screws fastened per bit to over 500,000

NOTE: For optimum bit life, we do not recommend exceeding 50% of minimum torsional strength.

TORX PLUS ? D R I V E O U T P E R F O R M S ACR ? P H I L L I P S II
A finite element analysis of the TORX PLUS? Drive System and the ACR? Phillips II drive was conducted to analyze the amount of stress encountered by both the driver bit and recess when subjected to certain loads. The results:

THE TORX PLUS DRIVE HANDLES SIGNIFICANTLY HIGHER TORQUE THAN THE ACR PHLLIPS II
Ultimate Torque (force at which the driver fails)
Ultimate Failure Torque (Nm)

Driver Bits at Proof Load of 32 Nm
ACR II Phillips showed high levels of plastic strain (shown in red) concentrated in very small areas of the driver bit. These highly localized strains are initiation points for cracks on the driver. The plastic strain levels in the TORX PLUS driver are lower and spread out more, so there is less chance the driver bit will crack.

TORX ACR PLUS Philllips Drive II

THE TORX PLUS DRIVER PROVIDES A LONGER FATIGUE LIFE THAN THE ACR PHILLIPS II
Driver Fatigue at Proof Load of 20Nm
Percentage of driver bit under plastic strain 10%

The ribs of the ACR Phillips II driver initiate stress risers. At 20Nm, this causes the plastic strains in the driver to be very large (6.0%). At the same load, the TORX PLUS Drive bit has a very low percentage of plastic strain (0.5%).
TORX ACR PLUS Philllips Drive II

Plastic strain causes permanent deformation to the driver that can shorten its life.

The ribs of the ACR Phillips II bit initiate stress risers

The curved surfaces of the TORX PLUS drive prevent stress risers

THE TORX PLUS DRIVE FASTENERS OFFER AN INCREASED NORMAL OPERATING LIFE
Fastener Recesses at Proof Load of 20Nm
Plastic strains on the ACR Phillips II fastener recess are fairly high and concentrated on the engaged rib. This will cause a similar result to what happens to the driver, with small cracks forming at these localized strain locations. If these cracks damage the protective coating of the fastener, it can allow corrosion which may reduce the normal operating life of the fastener. Plastic strains in the TORX PLUS fastener recess are almost three times lower and much more spread out. Although some permanent deformation does occur, the stress is spread out, so there is less chance of cracks forming.

On all analyzes, the materials for both the TORX PLUS and ACR Phillips II models represented standard steel with values equal to a Property Class 10.9 fastener. NOTE: All drawings are representative of actual FEA results.

TORX PLUS ? D RIVE O UTPERFORMS

THE

TORX ? D RIVE

A finite element analysis (FEA) of the TORX PLUS Drive System and the TORX Drive System was conducted to analyze the amount of stress encountered by both the drive bits and recesses. The TORX PLUS Drive System demonstrated: ? An average 25% increase in ultimate torsional strength of the driver bit. ? An average 25% increase in ultimate torsional strength of the total drive system, allowing for higher torque transfer and higher torque removal capability. ? An increase in fatigue life averaging 100% because of reduced stresses in the driver bit. ? Because of the circumferential load transfer of the TORX PLUS Drive System, the radial stresses are greatly reduced. This allows for thinner-walled recesses and demonstrates a more efficient drive system.

Force Vectors at 40Nm

TORX PLUS Drive

TORX Drive

The TORX PLUS Drive directs the forces in a more circumferential direction than the TORX Drive. Less force is passed into the fastener head and instead is utilized directly in rotating the fastener, resulting in a more efficient transfer of torque. This also allows thinnerwalled recesses to be utilized.

Transmitted Forces at 20Nm

At 20Nm, the TORX PLUS Drive has a very small percentage of the drive bit under stress, and no sign of internal yielding. The TORX Drive bit has a much higher percentage of the drive bit affected by the combined stresses (torsional, tensile, etc.) and also shows a small region that has internal yielding.

TORX PLUS Drive

TORX Drive

Radial Stress at 20Nm

The TORX PLUS and TORX designs show a similar radial stress value at the point of contact. However, the radial stresses for the TORX Drive System spread farther into the fastener recess over a larger area than the TORX PLUS Drive System.
TORX PLUS Drive TORX Drive

In fact, the radial stresses in the head quickly dissipate to zero for the TORX PLUS Drive System.

NOTE: The materials used for the TORX and TORX PLUS models were a typical thru hardened quench and tempered carbon steel, with properties representative of a Property Class 10.9 fastener. The material properties for the drive bit are for a modified S-2 material corresponding approximately to a hardness of Rockwell C60.
