براغي رأس سداسية 9/16-18 × 1-3/4" | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة بالكامل (25 / عبوة)

The yellow zinc finish on these grade 5 bolts is nice and uniform, and the fully threaded length made cinching down a bracket on my machinery a breeze with a socket. Good, solid threading all the way through, no burrs or hiccups.

Finally, a bolt that actually threads smoothly into the nut without binding halfway down. The yellow zinc coating looks solid, and I appreciate the full threading for getting a secure grip in the mounting bracket.

Just finished bolting down a heavy press with these, and the fully threaded design made it easy to get a tight hold in thick steel plates. The yellow zinc coating is a nice touch, looks clean and should resist rust in my shop.
