براغي رأس سداسي 3/8-16 × 8 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة جزئياً (15 / العبوة)

I needed some long bolts for a heavy equipment repair, and the 8-inch length on these was perfect. They threaded in smoothly with a socket and the hex head didn't strip at all. Nice solid feel to the grade 5 steel.

The yellow zinc coating on these bolts is really nice and even, makes them look clean on my equipment. They threaded smoothly into the tapped holes without any binding, which I always appreciate.

Used these to mount a gearbox on a frame and the grade 5 yellow zinc held up tight under heavy torque. The hex head gave a solid socket grip without any stripping, and the partial thread let the shank sit flush for alignment.
