7/8-14 X 10" 六角頭螺絲 | 美國製造 | L9級合金鋼黃鋅 | 部分螺紋 (15顆/包)

The yellow zinc coating on these is smooth and uniform, and the threads engaged perfectly on the first try with my impact wrench—no galling at all. Used two to secure a heavy-duty press base, and they held rock solid torque specs.

I needed longer bolts for a jig I was building at the shop, and these 10-inch cap screws fit perfectly. The yellow zinc coating looks solid, and the partial threading made starting the nut much easier than a fully threaded bolt would have.

The hex head on these bolts grips my wrench perfectly without slipping, and being USA-made gave me confidence in the quality. They threaded cleanly into my equipment with no binding. Exactly what I needed for a secure assembly job.
