When a Phillips is not a Phillips!

Step 15 ACR® Phillips®

Patented by the Phillips Screw Company to compliment the Phillips drive. ACR was developed for the aerospace industry to avoid costly head stripping and to assure easy insertion and removal of screws during assembly and maintenance. The advanced ACR Phillips system keeps the driver securely mated to the screw during fastener removal eliminating damaged screw heads and drives while preventing damage to costly panels, avionics and structures. The ribbed mating surfaces of the driver and screw head lock together providing greater maintainability. There are 3 types of the drive bit but the most common is for removal and driving.

Advantages and Disadvantages of ACR Phillips

Maintainers prefer the ACR Phillips system because they dont have to push hard on the driver, reducing fatigue and the risk of injury. The results are securely removed screws every time with lowered cost, more productive workers, fewer drill outs, and fewer problems to fix in overhaul. ACR Phillips screws are also compatible with common Phillips drivers allowing emergency modifications and repairs.
