M8 x 50mm ソケットショルダースクリュー | ソケットヘッド | ソケットドライブ | 合金鋼 (25本/パック)

Used a few of these as pivots for a custom jig in the shop and they spin smooth as butter, the ground shoulder makes all the difference. The hex drive seated cleanly and held torque without stripping. Solid little hardware for the price.

The precision-ground shoulder on these M8 screws made a perfect bearing surface for the gate hinge I built, and the hex socket drive let me torque them down evenly. Exactly what I needed for a clean, repeatable pivot point.

Used one as a pivot axle for a jig I threw together, and the precision-ground shoulder rides smooth with zero wobble. All 25 came in the pack with clean hex sockets and a consistent finish — worth the money if you need bearing surfaces.
