Inch sized UNC helicoidal wire thread inserts in stainless steel (helicoils) with screw lock
Reinforce the thread in low shear strength materials, such as aluminum, aluminum alloys, etc.
The self-locking thread insert is identical in construction and operating principle to the regular helical thread insert, but it also offers a braking action on the screw thanks to the particular polygonal configuration of one or more turns of the insert thread. In this way, the screw remains tightened with absolute reliability even in the presence of vibrations or shocks. The anti-unscrewing braking action remains even after numerous screwing and unscrewing operations
The self-locking thread allows you to eliminate the use of other locking elements, such as elastic washers or similar, remaining effective even in the presence of high temperatures
Wire thread inserts can be installed in the prepared holes using tools available in this section: Installation tools for thread inserts
For hole preparation we recommend our very precise STI drill bits, which ensure exact hole size and the best hold of the insert in the hole. The tapping of the hole can be done with the appropriate oversized taps for wire thread inserts. The list can be consulted at the following path: Thread insert taps and drill bits
