5/16" X 1 1/2" 內六角肩螺絲 | 內六角頭 | 六角驅動 | 18/8 不鏽鋼 (25 個/包)

The hex socket drive made these easy to install in a tight spot for a small pivot joint I was building. The 18/8 stainless finish looks clean and feels solid, no burrs on the threads at all. For the price per piece, they’re exactly what I needed.

The precision-ground shoulder on these screws made aligning the pivot on my jig absolutely effortless. Fit perfectly into the bearing surface I needed them for.

Had to redo a cabinet door hinge setup and these shoulder screws worked perfectly as the pivot points. The precision-ground shoulder is noticeably smoother than standard bolts.
