M6-1 X 14mm 內六角螺絲 | 圓頭內六角驅動 | 全牙 | 10.9級合金鋼鍍鋅 (600個/包)

The hex socket drive bites cleanly every time, no stripped heads even on the third reuse. Zinc plating looks uniform across all 600 pieces, and the 10.9 hardness gives me confidence in my tooling fixtures. Shipping was fast, but the box could use sturdier dividers to keep them from rattling loose.

Bought these for a custom jig I’ve been building, and the zinc plating is smooth enough that they threaded in without any binding. Class 10.9 strength gives me confidence they’ll hold up under repeated torque, and the 600 count means I’ve got plenty for future projects.

The hex drive took my Allen key without any stripping—perfect for mounting a small jig on my drill press. The zinc coating looks evenly applied, and all six hundred pieces arrived without a single burr.
