Richard ★★★★★

Used a pack of these to repair a few stripped holes in a jig I use daily, and they held up perfectly through several more assemblies. The mil-spec quality shows—every insert threaded in clean and sat flush, no wobble or cross-threading. For the price of a 50-pack, it's hard to beat the convenience o

Elizabeth M. ★★★★★

Had to chase a stripped bolt in some equipment and these inserts held up perfectly during installation. The mil-spec quality is obvious—each one seated cleanly without any deformation. Solid kit to have on hand for general fastening jobs.

Robert ★★★★★

I was a bit skeptical about these inserts for a general repair job, but the mil-spec construction held up perfectly when I torqued a bolt into a soft aluminum bracket. Each insert seated cleanly without binding, and having 50 in the pack means I've got plenty left for future projects.
