Customer Reviews (4.6 / 5 · 5 reviews)

Ryan P. ★★★★★

Installed a dozen of these 304 stainless inserts into some aluminum parts and the threads are holding perfectly under torque. The 50-count pack gives you plenty for a project plus spares.

Ruby G. ★★★★★

Installed a dozen of these 304 stainless inserts into cast aluminum today and they seated perfectly with no stripping. The helical design holds the bolt threads securely—feels much stronger than a standard tap. I've got plenty left for future assemblies.

Victoria ★★★★★

Finally got around to using these 304 stainless inserts for a heavy-duty assembly project, and they cut clean and held tight without any galling. The 50-pack is a solid value for the price, and the threads feel precise.
