Thread Repair Inserts

Thread repair inserts are helical wire inserts that restore worn or stripped internal threads. Available in metric (M) and inch (UNC, UNF) threads, they create a durable female thread for repeated fastening, reducing pull-out and stripping in aluminum, cast iron and steel.

Offered in multiple pitches and insert lengths (1D–3D) for blind or through holes, with material options such as stainless steel or bronze for corrosion resistance. Tang-style inserts for straightforward installation, from Baer.

Common in maintenance, machining and automotive repair. Select the correct size and pitch of the original thread, and match the insert length to the required engagement.
