M16 X 60mm カップポイントソケットセットスクリュー | 合金鋼亜鉛メッキ (25本/パック)

The cup point tip really digs in securely on the steel plate I mounted, and the zinc plating looks clean out of the package. Worked perfectly with a hex key in a cramped spot under the machine.

The hex socket drive made it easy to apply high torque even in a tight spot on my gear assembly. The cup point bit into the shaft securely and hasn't backed out at all. Exactly what I needed for a solid, vibration-resistant hold.

The cup point on these set screws bit into my pulley shaft perfectly and held fast under heavy load. The zinc plating looks clean and seems durable for workshop storage.
