M8 X 25mm 滾花杯頭內六角止付螺絲 | 合金鋼 (250顆/包)

I needed these for a jig I was building, and the knurled cup point bites into the shaft much better than plain set screws. The alloy steel feels solid and the 25mm length was exactly what my application required.

The hex socket drive made installing these in a tight engine compartment a breeze, and the knurled cup point grips the shaft securely without slipping. Exactly what I needed for precise adjustment.

The knurled cup point really bites into the metal nicely, and the hex drive made tightening them in my bracket a breeze. They were a good fit for my project, though the package seemed a bit short of the stated 250 count.
