Customer Reviews (5.0 / 5 · 5 reviews)

Evelyn ★★★★★

Had a stripped M8 hole in a gearbox housing, and these inserts cut a clean new thread on the first try. The 304 stainless material feels sturdy enough to handle repeated torque without deforming.

William U. ★★★★★

Pulled a stripped thread on an engine bracket and these 304 stainless inserts bit right into the aluminum without any galling. The pack of 100 is great to have on hand for future repairs.

Daniel ★★★★★

Installed a dozen of these into aluminum brackets and they grabbed perfectly without stripping. The 304 stainless feels sturdy enough for repeated assembly cycles.
