M5 X 10mm 全圓柱端內六角止付螺絲 | 合金鋼（500 / 包）

The full dog point tip aligned perfectly in my jig holes, making assembly noticeably quicker than with standard set screws. The hex drive held torque without stripping, even when I tightened them in a tight corner. These feel more robust than the usual hardware store variety.

The hex socket drive made installing these into a tight corner on my milling fixture so much easier than using slotted screws. Full dog point aligned perfectly in the dimples for a secure hold.

I needed a batch of set screws for a jig I’m building, and these M5 x 10mm with the full dog point grabbed tight without slipping. The alloy steel feels sturdy enough for repeated adjustments, and the hex socket makes it easy to drive them in even in cramped spots.
