ACR Phillips II® Fastener Drive System

Get a grip on your driving problems with the new ACR Phillips II® fastener driving system!

ACR Phillips II® screws and driver bits – the latest enhancements to the most popular fastener system in use throughout the world – offer the Assembly Industry an easy step in the quest for “continuous improvement” of their end products. But continuous improvement is not limited to components alone. “Quality” through continuous improvement is also crucial for fastener drive systems used for high-speed mass production of fastener-held assemblies.

The much-improved ACR Phillips® II fastener driving system is specifically designed to meet the demanding needs of the ever faster manufacturing process, which often results in cam-out and component surface damage, as well as scrapped components. The new recess gives the assembling manufacturer more efficient and secure driving, while allowing continuous use of this popular cross-recess screw-driving system and providing continuity of service.

  • The incorporated ACR Phillips II® System improves the off-angle driving efficiency of the screws in those difficult assembly locations which often cause out-of-line driving leading to reamed recesses, rusty recesses, burred screw heads, and injury. This ACR enhanced system perpetuates the proven efficient bit-to-recess finding required by the industry’s fastest (and getting faster) automated assembly machines.
  • Extended drive tool life. The ACR Phillips II® System’s unique recess and patented driver reduce cam-out occurrences. Cam-out is the action that damages and reduces the driver’s performance efficiency in the recess. Reduction of wear also means fewer driver bits needed per thousand screws driven, a further cost savings.
  • Reduced assembly operator fatigue. Cam-out damages both recesses and driver bits. The only way to compensate for this is for the operator to exert greater end-load pressure on the driving tool. This is not only tiring; it is an ergonomically unacceptable situation for operators to endure for a full working day.
  • Less rework and fewer scrapped components. The more efficient screw driving ACR Phillips II® System allows better fastener control to required torque levels, resulting in consistent clamp loads. This efficiency achieves more assemblies produced without the danger of cam-outs and “gun runs” occurring on expensive component surface finishes – and operators alike.
  • Easier and safer operator guidance. The typically demanding operator guidance of drill screws or thread-forming screws during drilling and assembly is now far easier and safer.
  • Improved manual and automated operations. Bit-to-recess finding, an inherent and invaluable feature of the cross- recess screw driving system ever since the first “Phillips” recessed screws appeared on the market, is a continued feature of the improved ACR Phillips II® recess.
  • Off-angle driving improvement. Precise axial alignment during screw driving and service removal is the optimum for torque transmission efficiency. However, ideal conditions are not always possible, especially when complex products are being serviced in the field. The new ACR Phillips II® recesses and drivers excel under such adverse conditions, ensuring screw removal and re-insertion with greater ease and safety.
