M5 X 5mm 杯頭內六角止付螺絲 | 合金鋼鍍鋅 (1000顆/包)

Used these to hold a jig together on the mill, and the cup point really bites into the workpiece without stripping. All 1000 arrived clean and zinc-coated, no burrs or bent threads—exactly what I needed for repeated adjustments in cramped spots.

Installing these into some aluminum brackets, the hex socket drive made it easy to get them snug without stripping anything. The zinc plating looks clean and should help resist rust in my workshop.

The cup point grips way better than the flat-tip screws I used before, and the hex socket let me torque them down in a tight bracket without stripping. A full thousand pack for this price is a solid deal, and the zinc finish looks clean on the machine.
