5/8-18 X 1/2" 半狗點內六角止付螺絲 | 合金鋼 (50顆/包)

I needed these for a tight spot on a machinery guard where a standard screw wouldn't stay put, and the hex socket drive made installation a breeze with my T-handle wrench. The half dog point seated securely enough that I didn't have to worry about it backing out under vibration.

The half dog point tip held perfectly in my jig's set-up, and the hex drive let me torque it down without any rounding. Exactly what I needed for a precise locking application.

I needed a screw that wouldn't strip during final adjustments, and the hex socket drive on these gives a solid, secure grip even in a tight spot. The alloy steel feels tough and the half dog point design seated cleanly into the countersink. Worked exactly as needed for a quick assembly project.
