براغي رأس سداسي 7/8-14 × 10 بوصة | صناعة أمريكية | فولاذ درجة 8 زنك أصفر (20/عبوة)

Tightened down a 3-inch flange coupling with these and they threaded in smooth as butter. The hex head gave my 1-1/8" socket a solid bite, and the Grade 8 steel feels like it could handle way more than I'm throwing at it.

I needed some heavy-duty 10-inch bolts for a machinery repair, and these grade 8s fit perfectly with no slop in the threads. The hex heads seated nicely with a socket wrench, and the yellow zinc coating looks solid.

The yellow zinc coating is evenly applied with no bare spots, and the grade 8 hardness shows when you're torquing them down. Threads ran clean into our equipment frame without any binding, and all twenty arrived looking perfect. These are the real deal for heavy fastening jobs.
