Patented Phillips Drive Systems
AMI is licensed by the Phillips Screw Company to manufacture fasteners using the following patented drive systems:
TRI-WING® TAMPER RESISTANT DRIVE SYSTEM
The ultimate part of fastener security.
For applications where screws and bolts must be torque-tight and tamper-resistant, there is no better choice than the TRI-WING® Tamper Resistant Drive System. The head strength and torque capability of the TRI-WING provides outstanding resistance to vibration with a unique tri-slot shape.
TORQ-SET® OFFSET CRUCIFORM DRIVE SYSTEM
Proven performance where screws or bolts must be torque-tight.
As its name implies, the TORQ-SET® Offset Cruciform Drive System features an offset cruciform configuration that provides greater strength than a cruciform design, ensuring superior torque tightness for today’s demanding applications.
ACR® RIBBED TORQ-SET® OFFSET CRUCIFORM DRIVE SYSTEM
Offers optimum torque while protecting against cam-out.
With the ACR® Ribbed TORQ-SET® Offset Cruciform Drive System, a specific sized driver inserts and removes each diameter fastener so that optimum torque is provided in every size. Interlocking ribs applied to the removal side of the driver bit and screw surface ensure fast removal even when the fastener is corroded, seized or frozen. This meets the demands of high torque applications without cam-out.
ACR® RIBBED PHILLIPS® CRUCIFORM DRIVE SYSTEM
Eliminates fastener recess damage and drill outs.
The ACR® Ribbed PHILLIPS® Cruciform Drive System advanced design keeps the driver securely mated to the screw during fastener removal, eliminating recess damage and damage to surrounding areas. The results are securely removed screws every time with lower costs, more productive workers and fewer drill outs.
