M6 X 12mm 錐點止付螺絲 | 合金鋼 (500 顆/包)

These set screws are perfect for locking down a shaft in a tight gear assembly. The hex socket drive handled the high torque I needed without slipping. For the price per piece for 500, the alloy steel feels like a solid value.

I needed cone point screws for a tricky jig adjustment, and the alloy steel feels sturdy enough for repeated use. The 12mm length paired with the M6 thread fit my application perfectly, and the hex drive held up well under torque.

Used a handful of these to secure a jig's adjustable stop block, and the cone point really bites into the metal. The hex drive let me torque them down firmly in a cramped space, though the 12mm length is a bit short for thicker materials.
