Customer Reviews (4.6 / 5 · 5 reviews)

Lily Z. ★★★★★

The hex head grabbed my socket wrench perfectly on the first try, and the 10.9 steel feels seriously tough for the machinery frame I'm rebuilding. Fully threaded all the way down, so I got solid grip even on a thicker bracket.

Charlotte V. ★★★★★

I needed a bunch of M18 bolts for a jig I was building, and the fully threaded design saved me from having to measure and cut each one. The hex heads gripped my socket wrench perfectly, and the zinc plating hasn't shown a speck of rust after a week of shop use.

Emma V. ★★★★★

These bolts feel properly solid, and the 10.9 grade is exactly what I needed for a heavy equipment jig. The hex heads grab a socket cleanly with no stripping, and the zinc coating has a consistent finish across all 120 pieces.
