M8 X 30mm 內六角肩螺絲 | 內六角頭 | 內六角驅動 | 18/8 不鏽鋼 (25 顆/包)

I needed smooth bearing surfaces for a small pivot assembly, and these screws delivered—the precision-ground shoulder runs perfectly true. The hex socket makes installation straightforward, and the 18/8 stainless looks great.

The shoulder on these is machined incredibly smooth—it slides through a bearing bore with zero slop. I've used a few as axle replacements on a garage project and the stainless finish hasn't shown a single rust spot after a damp week.

These made perfect pivot pins for a jig I’m building, and the hex socket drive let me torque them down without stripping. The shoulder on each one feels machined to a tight tolerance, and the stainless finish gives them a solid, clean look.
