براغي رأس سداسية 3/8-16 × 7/8" | صناعة أمريكية | فولاذ درجة 8 مطلي بالزنك الأصفر | ملولبة بالكامل (100 / عبوة)

The threading on these cap screws is clean and consistent across all 100 pieces, which saved me time during a truck mount assembly. The Grade 8 yellow zinc finish feels robust and hasn't shown any flaking after tightening with an impact wrench. Price per piece is fair for hardware this solid.

These are my go-to bolts for anything that needs to hold tight under vibration. The hex heads give a solid grip with a socket, and the yellow zinc looks sharp on my tractor repairs.

The threading is clean and consistent across all 100 bolts, so no chasing threads needed. Used these for a heavy jig build and the Grade 8 yellow zinc finish held up well under the wrench.
