Customer Reviews (5.0 / 5 · 5 reviews)

Jason C. ★★★★★

Packed these into a few stripped engine block holes and they gripped perfectly—the 304 stainless held up without any deformation during installation. The 100-count package means I've got plenty left for future repairs, and the consistency between each insert is spot-on.

Ruby ★★★★★

The 304 stainless steel feels solid and corrosion-resistant, which is exactly what I needed for general assembly work. Every insert seated smoothly without any binding, saving me a ton of time on a recent project.

Sebastian ★★★★★

Clean threads on every one of the hundred, and the 304 stainless steel finish looks uniform even under a magnifying glass. These held up through a couple of assembly and disassembly cycles without a single strip, which is exactly what I needed for general fastening work.
