1-1/2-6 X 6" 六角頭螺絲 | 美國製造 | L9級合金鋼黃鋅 | 半牙 (5個/包)

These hex bolts are seriously beefy; the Grade L9 alloy steel is noticeably harder than the standard hardware store stuff. I used a few for mounting a heavy vise to my workbench, and the yellow zinc coating looks like it'll resist rust well. The partial threading made it easy to get a solid bite.

These bolts handled the torque on my press jig perfectly—the L9 alloy steel feels way tougher than the hardware store stuff I usually grab. The partial threading made alignment a breeze, and the yellow zinc coating looks clean.

I needed some heavy-duty fasteners for a gearbox rebuild, and these Grade L9 screws handled the torque without any issues. The hex head grips nicely with a socket, and the partial threading made them easy to position. A solid choice for the price.
