5/8-11 X 3" 重型六角頭螺絲 | 美國製造 | A307 B級鋼原色 | 部分螺紋 (75個/包)

I needed heavy-duty bolts for a steel rack rebuild, and these 5/8-11 screws fit perfectly with no play in the holes. The partially threaded design worked great for clamping thick flanges without bottoming out, and the plain finish held up to a few accidental hammer taps.

The threads cut smoothly and the hex head grabbed my socket perfectly without any wobble. I used these for a heavy equipment mount and they held solid without stripping under torque. Solid value for a full package of quality industrial bolts.

Needed some heavy-duty bolts for a trailer hitch repair, and the 3-inch length was perfect for going through the frame. The partially threaded design made installation a breeze since the smooth shank sat flush where it needed to.
