براغي رأس سداسي 5/8-18 × 1-1/2 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة بالكامل (25/عبوة)

The yellow zinc coating on these bolts held up perfectly when I tightened them with an impact wrench, no stripping or chipping. They threaded smoothly into the equipment frame without binding, exactly what I needed for the job.

Needed these for a heavy equipment repair, and the Grade 5 steel with yellow zinc held up perfectly under torque. Full threading made installation quick, and the hex head fit my socket wrench without any stripping.

Took these out of the package and the threads are perfectly clean, no burrs, so they drove in smoothly with a socket. The 5/8-18 size was exactly what my jig needed and the fully threaded length gave me solid bite the whole way.
