3/4-10 X 6" 六角頭螺絲 | 8級鋼鍍鋅 | 部分螺紋 (50個/包)

Needed these for a heavy-duty jig I’m building, and the partially threaded design gave me just the right grip without bottoming out. The hex heads turned smoothly with a socket, and all fifty bolts had clean, even threads.

Zinc plating looks uniform across all fifty, and the threads on the partially threaded section were clean enough that I didn’t have to chase a single one before torquing them onto a skid loader attachment. Grade 8 heft is obvious even before you get a wrench on the hex head.

These bolts cinched down perfectly on my hydraulic press mount, the Grade 8 steel feels way tougher than the hardware I normally grab. The zinc coating is a nice bonus, no rust worries in my damp basement shop after a few weeks.
