Jason J. ★★★★★

Needed a batch of fully threaded M18 bolts for a heavy equipment repair, and these Class 8.8 hex heads fit the socket perfectly without any stripping. The zinc coating looks even and held up well during a tough install.

Michael H. ★★★★★

The zinc plating on these M18-1.5 x 40mm screws has held up perfectly in my outdoor machinery project, with zero rust after a few weeks of rain. The hex head gave my socket wrench a solid grip for torquing them down evenly.

Elizabeth ★★★★★

Used these M18-1.5 x 40mm bolts for a heavy equipment lift point, the fully threaded grip made alignment much easier than with partially threaded ones. The zinc plating held up fine to a few days of light rain during assembly. Solid fasteners for the price, no issues with the hex head stripping.
