M2 X 3mm カップポイント六角穴付き止めねじ | 18/8 ステンレス鋼 (250個/袋)

Finally got around to using these for a jig build—the M2 thread was a perfect fit and the cup point really bites into the metal. They’re tiny but tough, and the 250 count means I won’t run out anytime soon. Exactly what I needed.

The hex socket drive is a lifesaver for seating these M2s in tight spots—the cup point grips the shaft like a dream. I torqued them down on two small pulleys and not a single one has budged. Bag of 250 is plenty for my whole bench.

Used these to replace worn grub screws in a small indexing jig, and the cup point bites down firmly on the shaft without slipping. The hex socket drive is a lifesaver for getting them torqued in a tight spot, and the 18/8 steel feels solid. Packaging was neat, with all 250 accounted for.
