7/8-9 X 10" 六角頭螺絲 | 美國製造 | PFC9合金鋼黃鋅 (10個/包)

Threads were clean, no burrs, and they seated flush against the flange without any binding. I torqued three of them to spec on a press frame and the yellow zinc finish held up nicely under the wrench. Solid, heavy feel for the price.

The 10-inch length on these hex cap screws is exactly what I needed for a heavy-duty jig I’m building, and the hex head drove in without any stripping. The yellow zinc coating looks solid and corrosion-resistant right out of the package.

I’ve ordered a lot of fasteners over the years, and the yellow zinc finish on these is what stood out first—uniform and tough. The threads cut clean and the 10-inch length gave me plenty of grip on the frame I was bolting down. Solid choice if you need something that won’t fight back on assembly.
