3/8" X 5" 內六角肩螺絲 | 內六角頭 | 內六角驅動 | 18/8 不鏽鋼 (25/包)

I replaced a worn-out pivot on my heavy-duty clamp with one of these, and the precision-ground shoulder made it fit perfectly. The 18/8 stainless steel feels solid enough to handle repeated use, and the hex drive was easy to tighten without stripping.

These were exactly what I needed for a bearing surface on a small jig I built. The precision-ground shoulder slid right into place with zero play, and the stainless finish looks clean.

I’ve used these as pivot pins on a couple of jigs and the shoulder is dead-on accurate, so everything spins smooth without any wobble. The 18/8 stainless finish looks clean and should hold up fine in the shop.
