Customer Reviews (4.6 / 5 · 5 reviews)

Kevin ★★★★★

Installing these into a cracked plastic bracket was way easier than I expected, they bit in cleanly and held tight. The 18/8 stainless gives me confidence they won't rust out in a damp shop. Fifty in the pack means I've got plenty left for future repairs.

Thomas ★★★★★

Finally got around to using these inserts for a repair project on thin aluminum, and the 18/8 stainless steel feels much more robust than the zinc-plated ones I've tried before. They tapped in cleanly with no stripping.

Jacob ★★★★★

Needed a solid fix for some thin metal panels and these 18/8 stainless inserts held beautifully under torque, way better than cheap aluminum alternatives. The 4-40 threads cut cleanly with no galling on the first try.
