Metric helicoidal Tangless Self-locking wire thread inserts in stainless steel (tangless helicoils)
Reinforce the thread in low shear strength materials, such as aluminum, aluminum alloys, etc. Allow to restore a damaged thread to its initial size, ensure extremely reduced intervention time
With Tangless thread insert, there is no need to determine where the top and bottom of the insert are, it can be used equally on both sides. As a result Tangless inserts offer greater working speed compared to regular thread inserts
Tangless thread inserts are advantageous in applications with blind holes and where thread insert take the entire length of the hole, where therefore there is not enough space for accurate removal of the tang
The Self-locking Tangless thread insert is identical in construction and operating principle to the regular Tangless 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
Respond to military and aerospace standards
Tangless inserts are more expensive than traditional ones and require specific Tangless installation equipment, so they are recommended for applications with large volumes
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
