Raptor™ Claws Are Now Available For Flat Head Socket Cap Screws

Raptor™ Claws Create the Strongest Security Fastening System
We developed Raptor™ claws underneath our BH security screws to eliminate the need for a lock washer and tighten the load an extra 20%-30%. The performance of Raptor™ yielded such positive responses from our customers, we figured out how to add it to our FH socket cap screws.
Originally we hoped to attain a 20% improvement in hold. To our surprise, the removal torque of Raptor™ claws on FH socket cap screws is the DOUBLE the insertion torque.
We took two M12 hardened flat head socket cap screws and tightened them into cold rolled steel.
™™
The M12 bolt without Raptor™ claws was torqued to 75 ft./lbs. and removed at 65 ft. /lbs.
The flat head with our Raptor™ serrations would not budge at 140 ft./lbs. We pushed until the bit broke.
Our Conclusion:
A FH screw with our Raptor™ feature causes the head to flex downward and tighten at the same time. Torque values reached are 1.75x the installation torque, creating a fastening system more secure and stronger than any other security fastener ever made. The added strength is ideal in high security applications.
Tips When Installing Raptor™
- Don’t torque the FH too tight. You won’t be able to get it off.
- If you can’t get it off, unloosen the nut at the back.
- Make sure everything is lined up before giving the final tug on the wrench.
