براغي تثبيت رأس أسطوانية بنقطة كوبية M10 × 80 مم | فولاذ سبائكي مطلي بالزنك (50/عبوة)

The cup point bites into the shaft really well, so I don't worry about these backing out under vibration. The zinc plating looks clean and even across all fifty pieces, and the 80mm length gave me plenty of thread engagement for my setup.

The hex socket drive on these screws allowed me to apply serious torque without stripping, even in a tight spot. The cup point bit into the shaft firmly, and the zinc plating held up well against a little moisture during installation.

These set screws are perfect for locking down a sprocket on a shaft. The hex socket drive lets you really torque them in without stripping, and the 80mm length gives plenty of bite. Exactly what I needed for a heavy-duty repair.
