Hazel ★★★★★

I’ve been using these inserts for a batch of aluminum panels, and they’ve held up perfectly so far. The 304 stainless steel feels solid and the threads catch cleanly every time.

Zoe I. ★★★★★

Installed a dozen of these into some aluminum engine parts and they bit perfectly without any cross-threading. The 304 stainless feels solid and the 1000-count pack will last me through many more repair jobs.

Victoria F. ★★★★★

I needed a bulk pack for repairing stripped threads on some older equipment, and these held up perfectly during installation without any galling. The 304 stainless steel feels solid and the 1000-count package will last me years.
