1"-14 X 7-1/2" 六角頭螺絲 | 美國製造 | 8 級鋼 黃鋅 (20 個/包)

I needed bolts that could handle heavy equipment torque, and these Grade 8 steel cap screws threaded in cleanly without any binding. The yellow zinc coating looks consistent across all twenty pieces. Exactly what I expected from US-made fasteners.

The hex heads fit my socket perfectly, and the Grade 8 steel feels solid when torquing down heavy equipment mounts. No stripping or rounding, just clean threading all the way—exactly what I needed for a secure hold.

I needed a dozen of these for a heavy-duty press rebuild and they threaded in smoothly without any binding. The 1-inch diameter and Grade 8 rating give me confidence they'll handle the load.
