Customer Reviews (4.2 / 5 · 5 reviews)

Sebastian ★★★★★

These little bolts fit perfectly in the bracket I’m using to mount some metal shelving. The zinc finish seems decent and the threading is clean all the way through. Just what I needed for the job.

Claire ★★★★★

Had to replace a few worn bolts on my tractor's mower deck, and these zinc-plated ones fit perfectly without any binding. The 50-count pack is more than enough for future projects too.

Joshua ★★★★★

The threads are cut clean all the way down, so they grabbed perfectly when I bolted two steel brackets together. Nice even zinc coating on all 50 pieces, and the hex heads seated squarely with my socket.
