مسامير رأس كبس سداسية 5/8-11 × 8" | صناعة أمريكية | سبائك فولاذ درجة L9 مطلي بالزنك الأصفر | ملولبة جزئيًا (25/عبوة)

Installed these on a press brake clamp; the threads caught cleanly and the L9 grade held torque without any stretch. Yellow zinc finish looks solid and hasn’t shown any rust after a few days in a humid shop.

Used these for a heavy-duty fixture bolting job and the L9 alloy steel held up perfectly under torque. The zinc finish is clean and consistent across all 25 bolts.

The partial threading on these 8-inch bolts gave me just the right grip depth for my heavy equipment frame, and the yellow zinc finish looks clean and durable. They seated smoothly with a socket wrench, no binding or stripped edges.
