براغي رأس سداسي 7/16-20 × 1 بوصة | صناعة أمريكية | سبيكة فولاذ PFC9 مطلي بالزنك الأصفر (100 / عبوة)

These bolts threaded perfectly into a tight spot on an old press without any binding, and the yellow zinc coating looks like it will hold up well against grime. Exactly the grade I needed for a heavy repair.

Used a full pack rebuilding a conveyor drive and every single one threaded clean without a single bad batch. The hex heads held up great under a impact wrench with no rounding. These are my new go-to for any 7/16 job.

The yellow zinc finish looks sharp on my equipment and hasn't shown a speck of rust after a month of shop use. Threads cut cleanly into both my wrench and a socket without any binding, and all 100 pieces arrived with consistent machining.
