5/16-18 X 3/8" Halve hondenpunt stelschroeven | Gelegeerd staal (250 / Pkg.)

The hex socket drive made installing these in tight spots on my workbench so much easier than using a regular wrench. Pack of 250 gives me plenty for future projects and the alloy steel feels solid.

The half dog point tip seated perfectly into my jig without walking, and the alloy steel feels sturdy enough to handle repeated adjustments. I used these for securing a metal fixture, and they held tight under vibration. Exactly what I needed for precision fastening.

The hex socket drive made tightening these into a tight spot on my jig much easier than using a standard wrench. They held up well during a high-torque test run, and the half dog point seated perfectly in the mating hole.
