M6 X 20mm 錐端內六角止付螺絲 | 合金鋼 (250顆/包)

Packed 250 of these in one box, and every single one has a clean, sharp cone point that seats perfectly in the pilot hole. The alloy steel feels solid, and the hex socket drive grabs my Allen key without stripping, even when I’m torquing them into a tight bracket.

Had to swap out some old set screws on a machine slide, and these M6 cone points grabbed better in the countersink than the originals ever did. The hex socket drive let me get full torque in a cramped spot without stripping.

The cone point on these M6 screws really bites into the shaft, giving me a solid hold for a jig adjustment I was struggling with. All 250 pieces in the pack are neatly threaded and the hex drive works smoothly in a tight spot.
