M12 X 25mm ソケットショルダーねじ | ソケットヘッド | ソケットドライブ | 18/8 ステンレス鋼 (25本/パック)

Finally got around to using these as pivot pins for a small jig I was building, and the precision-ground shoulder made for a noticeably smooth rotation. The hex socket drive seated my Allen key perfectly without any wobble.

Perfect alignment for a custom gate hinge I’m building—the precision-ground shoulder gives a smooth, dead-on rotation with zero play. These socket heads let me use an Allen key for easy tightening in tight spots. Might grab another pack for the next project.

Had to swap out a worn pivot on a clamp jig, and the precision-ground shoulder made the fit exact. These M12 screws are holding up way better than the hardware store stuff I'd used before.
