MS21209F5-10 | إدراجات حلزونية عسكرية المواصفات | فولاذ مقاوم للصدأ 304 (50 / عبوة)

Installed a few of these into stripped threads on a truck bracket and they bite really well. The 50 pack is generous and the 304 stainless held up better than the cheap steel ones I’ve tried before.

Tapped out a bunch of stripped threads in some old steel brackets, and these 304 stainless inserts held up without a single one spinning loose. The 50-pack is a solid value for how much general repair work I’m doing.

Used these to repair a few stripped threads on a workbench assembly, and the 304 stainless seems like it will hold up well. The 50-count pack is plenty for small projects. Only wish they came with a better insertion tool.
