M3 x 12mm フラットポイント六角穴付き止めねじ | 18/8 ステンレス鋼 (1000個/パッケージ)

Had to swap a stripped screw on a robotics jig, and these 18/8 stainless flat points seated perfectly without slipping. The 1000-count bag should last me years for small repairs.

The flat point tips seated perfectly flush against the plate, and the hex socket gave me solid grip even in that cramped corner. I've used cheaper set screws that stripped on the first turn, but these 18/8 stainless ones handled repeated adjustments without a hint of wear. A full thousand in the bag

Finally, a set screw that actually holds tight without stripping. The hex socket drive let me get these M3s snug in a cramped servo mount, and the stainless build means no rust worries.
