براغي رأس سداسي 1-1/8-7 × 2-1/4 بوصة | صناعة أمريكية | درجة 8 فولاد أصفر زنك (35/عبوة)

I needed some heavy-duty bolts for a press jig rebuild, and these grade 8 cap screws threaded in smooth and snug. The hex heads held up well under a high-torque impact wrench without any stripping or deformation.

The yellow zinc coating on these grade 8 bolts is evenly applied and the threads cut cleanly into my equipment frame without any binding. They're solidly built and have a reassuring heft that gives me confidence in the machinery I'm assembling.

Finally, a hex bolt that doesn't strip out on the first turn—the Grade 8 steel feels rock solid under a socket wrench. These are going to hold up much better than the cheap hardware I've been fighting with on my shop equipment.
