M12 x 45mm 錐點內六角止付螺絲 | 合金鋼 (100顆/包)

The cone point tip started perfectly centered on my work piece, saving me from pilot holes in a tricky spot. They bit into the steel framing with impressive grip, and the hex socket held up under my impact driver without stripping.

The hex socket drive let me apply way more torque than I expected without stripping, which is huge for tight spaces. These cone point tips started cleanly in steel without any wandering. Solid buy for a project where surface finish matters.

Finally, a set screw that holds tight in my precision adjustment jigs; the hex socket drive lets me torque it down fully without stripping. The cone point bites into the shaft cleanly, keeping everything locked in place during vibration.
