Steven R. ★★★★★

Threads cut clean and the hex heads seated perfectly with a standard socket wrench—no stripped corners on any of the 80. Partial threading gave just the right grip for the heavy flange I was bolting down. Couldn't ask for better consistency from a bulk pack.

Madison ★★★★★

I needed some heavy-duty bolts for a piece of farm equipment, and these M18 hex heads fit the bill perfectly. The class 8.8 steel feels strong and the threading on the shank is clean, no burs or issues.

Christopher P. ★★★★★

The 80-count box is a solid deal for the shop, and the partially threaded design gave me just the right grip length for a steel frame build. The hex heads seated cleanly with a socket wrench, no stripping or wobble.
