براغي رأس سداسي 7/16-14 × 7 بوصة | صناعة أمريكية | فولاذ درجة 8 أصفر زنك (125/عبوة)

Tapped these into a jig for a press rebuild and the threads were clean, no binding. The hex heads have a nice sharp profile that grabs the socket tight. Yellow zinc finish looks uniform across all 125 pieces too.

Put these on a heavy-duty conveyor frame that sees constant vibration, and the yellow zinc coating still looks fresh after three months. The threads cut cleanly with no binding, and having seventy-five in the pack meant I had spares for the next job.

The hex head on these grade 8 bolts fits my socket perfectly, and the yellow zinc coating looks clean and durable. Using them to fasten a press frame, and they drove in smoothly without any binding. Solid buy for the price per pack.
