Customer Reviews (4.6 / 5 · 5 reviews)

Kevin P. ★★★★★

These 304 stainless inserts bit into the aluminum cleanly without any cross-threading. Installed a full pack over the weekend and every single one held tight.

Olivia E. ★★★★★

Used a few of these to reinforce some high-wear threaded holes in a jig, and the 304 stainless held up perfectly without any galling. The kit came with a generous 100 pieces, which should last through many future projects.

Sofia O. ★★★★★

Repaired the stripped threads on a metal frame with these and the 304 stainless steel held up perfectly through the whole install. The helical design seated cleanly with no binding, which made the job a lot less frustrating than I expected. Solid batch of 100 for the price, no duds in the pack.
