Sebastian F. ★★★★★

Packed my torque wrench for these M18-2.5 x 55mm hex heads, and the full threading grabbed evenly right from the start. The 120-count package means I’ve got extras for the next job.

Joshua I. ★★★★★

The hex head on these is a perfect fit for my socket set, and the 55mm length was exactly what I needed to secure some heavy equipment. All 120 screws arrived clean and well-threaded without any burs or defects.

Leo ★★★★★

Needed a solid set of bolts for a heavy equipment repair and these M18s held tight without stripping. The Class 10.9 steel feels noticeably tougher than the standard hardware I've used before.
