براغي رأس سداسية 1/4-28 × 7-1/2 بوصة | صناعة أمريكية | فولاذ درجة 8 زنك أصفر (275/عبوة)

These bolts were exactly what I needed to finish a custom jig for my press. The hex heads gripped perfectly with a socket and the Grade 8 steel feels incredibly solid.

Had to order these for a repair on an old milling machine, and the hex heads fit my socket perfectly without any slip. The yellow zinc coating looks nice and seems like it’ll hold up well.

The threads cut clean and the heads grabbed a socket perfectly on first try, no galling on a stubborn mount. Yellow zinc looks uniform across all 275 pieces, and the Grade 8 feel is reassuring when you're torquing them down for real. Exactly what I needed for a production fixture.
