Finally a set of inserts that actually holds tight in aluminum; I've used about 40 so far and each one installed cleanly without any cross-threading. The 304 stainless feels much sturdier than the zinc versions I've tried before.

Used a full pack repairing stripped threads on a machine base and every single insert seated perfectly with no cross-threading. The 304 stainless finish feels tough enough for daily assembly work, and the 200-count box means I won't be reordering anytime soon.

The 304 stainless steel feels solid and corrosion-resistant, which is exactly what I needed for a general assembly job. I've used about 50 of these so far and every single one threaded in cleanly without any binding or stripped threads.
