M6 X 35mm 杯頭止付螺絲 | 18/8不鏽鋼 (250顆/包)

Used these to lock down a motor mount and the cup point really bites into the shaft, no slipping after a week of vibration. The 18/8 stainless is clean and the hex drive took an Allen key without stripping even with a good amount of torque.

I needed some stainless fasteners that wouldn't humiliate me when I inevitably overtighten them, so these hex socket screws felt reassuringly robust. The cup point tip seated cleanly into the metal frame without any skipping, and the 18/8 material looks like it'll handle the moisture from my shop.

The hex socket drive made these easy to cinch down even in a tight spot, and the cup point grips the surface without slipping. They’re a solid 4 stars for me, though I wish the bag they came in had a resealable closure.
