5/16-24 x 1-1/2英吋 全狗點內六角止付螺絲 | 合金鋼 (100個/包)

I’ve bought a lot of set screws that strip or wobble on the hex key, but the full dog point on these seated perfectly flush into my coupling. All 100 came clean with no burrs on the threads, and the alloy steel feels tough enough to hold up under repeated adjustments.

The hex socket drive made torquing these down in a cramped mounting bracket surprisingly easy, and the full dog point seated perfectly into the mating hole. All 100 pieces came with clean threads and no burrs, so I didn’t have to chase a single one.

I needed these for a precise jig assembly, and the hex socket drive made tightening them in a cramped corner so much easier than a standard bolt. The alloy steel feels really solid too.
