5/8-11 X 7/8" 半狗頭孔內六角止付螺絲 | 合金鋼 (50入/包)

The hex socket drive made torquing these down in a cramped machine frame way easier than wrestling with a wrench, and the half dog point seated cleanly into the bore without any wobble. Came in a sturdy 50-count box that'll last me through several jobs.

The half dog point tip seated perfectly into my shaft keyway on the first try, and the alloy steel feels plenty tough for the torque I put on them. Threads were clean with no burrs right out of the pack, so the 50-count was worth every penny for my rebuild job.

The hex socket drive is a lifesaver when you're torquing these down in a cramped spot, and the half dog point seats perfectly every time. I grabbed a 50-pack for a fixture build and haven't had a single one strip or wobble. Exactly what I needed.
