Customer Reviews (4.8 / 5 · 5 reviews)

Lucy ★★★★★

The nylon patch is a nice touch—keeps them tight without needing thread locker, and the black oxide finish looks clean on my tooling fixtures. Packed well enough that none were scratched.

Stella X. ★★★★★

Bought these for a jig I’m building and the thermal black oxide finish looks even better in person than on screen. The hex socket drive gripped cleanly with no stripping, and the nylon patch kept them snug during a test run. Exactly what I needed for precision work.

Mia K. ★★★★★

The nylon patch is holding tight on a jig I built, no loosening after a week of heavy use. These bolts feel solid and the black oxide finish looks clean.
