براغي رأس سداسي 7/16-20 × 2-3/4 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (50 / عبوة)

The hex head grips perfectly with my socket, and the yellow zinc coating looks like it will hold up well against corrosion. These threaded in smoothly on my equipment assembly job with no binding or stripped threads.

Used a few of these to tighten down a bracket on my trailer hitch, and the hex head grabbed my socket nicely without slipping. The yellow zinc finish seems tough enough to handle some weather, and the partial threading made alignment easy. Happy with the grip these 50 bolts give for the price.

The partial threading saved me a lot of time aligning the bracket on my press; the yellow zinc finish also looks clean and resists corrosion well.
