Hazel ★★★★★

The zinc plating on these grade 8 bolts looks clean and even, no flaking or rough spots across the whole box of 450. I used them to bolt down a steel workbench frame, and the 2-1/2" length with partial threads gave me a solid bite without bottoming out.

Adam ★★★★★

The hex head works perfectly with my socket set, and the zinc coating looks clean so far. Packed 450 of these Grade 8 bolts to a box, which is plenty for my shop projects.

Daniel A. ★★★★★

Grabbed a box of these for a big equipment rebuild and they drove in true without any binding. The grade 8 steel feels rock solid, and having a full 450 pieces in one package saved me multiple trips to the supply house.
