1/4" X 1 1/2" 內六角肩螺絲 | 內六角頭 | 內六角驅動 | 18/8不鏽鋼 (25個/包)

The precision-ground shoulder on these screws made aligning a jig's pivot arm dead simple, no wobble at all. Perfect for my small machine build where I needed a reliable axle.

Used a few of these as pivot points in a custom jig, and the shoulder fit snugly without any play. The stainless steel gives them a nice, clean look that resists corrosion.

The shoulder is ground perfectly smooth, so the 1/4-inch shaft spins freely in my hinge joint without any wobble or binding. These stainless screws feel substantial and the hex socket drove in cleanly with no stripping.
