1-1/4-7×5英寸六角頭螺絲 | 美國製造 | 8級鋼黃鋅（15／包）

These bolts are the real deal—the threads engage super clean and the hex head gives you a solid bite with a socket, no slipping at all. They’re noticeably beefier than hardware-store stuff, and knowing they’re Grade 8 means I’m not second-guessing them on heavy equipment.

The yellow zinc finish on these cap screws is holding up well in my outdoor equipment, even after some wet weather. I used a socket drive to install them, and the hex head grabbed perfectly without stripping. For heavy-duty fastening, these Grade 8 bolts feel like serious overkill in the best way.

These bolts are really solid, the Grade 8 steel feels noticeably tougher than the hardware store stuff. The yellow zinc coating looks good and should hold up fine on my trailer hitch assembly.
