M6 X 35mm 滾花杯頭內六角止付螺絲 | 合金鋼 (250 顆/包)

These screws fit perfectly for securing a cam lock on my workbench, and the knurled cup point really bites into the metal. The hex drive made tightening them down in that tight spot a breeze.

I needed a longer set screw for a jig I was building, and these M6x35mm pieces fit perfectly. The knurled cup point really bites into the shaft without damaging it, and the hex socket makes installation easy even in cramped spots.

The knurled cup points gripped the metal surface way better than I expected, even on slightly worn parts. Used a full box setting up jigs on a milling table and not a single one stripped or backed out under heavy load. These are exactly what you need for industrial-grade fastening jobs.
