M20 x 50mm 插座肩螺栓 | 插座頭 | 插座驅動 | 合金鋼 (10入)

Used one as a pivot in a custom jig I'm building, and the socket drive made installation much cleaner than dealing with a hex head. The 50mm length was exactly what I needed for this application.

The precision-ground shoulder made these perfect as axle pins for my custom jig—hardly any play and they spin smooth. Fit perfectly in the M20 bearings I had, and the hex drive lets me torque them down without stripping. Solid quality for the ten-piece pack.

Installed these as pivot points on a custom jig and the hex drive made tightening them a breeze. The alloy steel feels solid and the shoulder's surface finish is perfectly smooth.
