براغي رأس سداسية 1/2-20 × 2-1/4 بوصة | صناعة أمريكية | PFC9 من سبائك الفولاذ مطلي بالزنك الأصفر (50/عبوة)

Needed these for a heavy machinery repair and the threads were clean and precise right out of the box. The hex head fit my socket perfectly with no slop or wobble.

The yellow zinc coating looks great and seems like it will hold up well in my shop environment. These hex head screws seated perfectly with my socket wrench, and having a full 50-count box means I won't run out mid-project.

These hex bolts threaded perfectly into my machinery without any binding, and the yellow zinc coating looks really durable. The 1/2-20 thread fit was spot on for the equipment assembly I was working on.
