براغي رأس مقبس M6-1 X 20mm | محرك سداسي | ملولبة بالكامل | سبيكة فولاذية فئة 8.8 مطلية بالزنك (400 / عبوة)

These arrived exactly as described, and the hex socket drive made tightening them into my jig a breeze. The zinc plating looks clean and uniform across all 400, no rust or burrs visible. Perfect for precision work.

These fit perfectly in my 3D printer's aluminum extrusion frame. The 20mm length was spot on for securing the corner brackets, and the hex drive made installation quick and easy. All 400 screws in the box were consistently threaded and zinc coated.

Needed a full box for a fixture build and these came out of the bag perfectly clean, threads all intact and the zinc coating looks uniform across all 400. The hex socket took the Allen key without any stripping, and at Class 8.8 they feel solid for the jig work I'm doing.
