M6 X 10mm 全狗點內六角止付螺絲 | 合金鋼 (500/包)

Installed these M6 set screws to lock a gear on a shaft, and the full dog point bites perfectly without walking loose. The alloy steel feels really solid compared to cheaper zinc ones I've used before.

I needed a full dog point tip for a critical alignment, and these M6 set screws gripped perfectly without slipping. The hex socket drive let me torque them down securely in a cramped spot, and the alloy steel feels solid, not cheap.

The hex socket drive made these easy to install in a tight spot, but a few screws had slightly inconsistent threads that took extra effort to seat. They feel sturdy enough for light to medium use, though I’d check batch quality if you need precise fitment every time.
