M24 X 80mm 六角凹頭肩螺絲 | 六角凹頭 | 六角凹頭驅動 | 合金鋼 (5 件/包)

I used these as bearing surfaces for a custom jig, and the socket drive made tightening them into tight spaces surprisingly easy. The 80mm length was exactly what I needed for this application.

The shoulder on these screws is machined so precisely that the pivot I built spins with zero wobble. They feel incredibly solid in the hand, exactly what I needed for a heavy-duty axle application.

These are surprisingly hefty, the ground shoulder is a nice tight fit in a reamed hole. Perfect for a steady axle on a heavy-duty assembly fixture.
