Leo S. ★★★★★

Went through the whole box mounting brackets for a conveyor line, and every single one seated cleanly in the hex drive without stripping. The zinc plating held up fine against the occasional wrench slip, no rust spots after a couple of damp days. Exactly what you want when you need 300 fasteners tha

Evelyn ★★★★★

Used these to mount a steel workbench frame and every single bolt threaded smoothly into the nuts without any binding. The 40mm length gave just enough bite for thick brackets without needing washers.

Stella ★★★★★

Zinc plating looks clean and consistent across all 300 pieces, and the fully threaded design made assembly on my jig fixture much easier than dealing with partial threads. Packed securely in a box without any bent heads, which I appreciate for bulk hardware.
