براغي رأس سداسي 1/2-20 × 1 بوصة | فولاذ درجة 5 مع طلاء زنك أصفر | ملولبة بالكامل (50 / عبوة)

Needed a handful of these to finish a small jig I was building, and the hex heads sat perfectly flush in the countersink without binding. The threads are cut clean and the zinc coating looks like it will hold up just fine on the shop floor.

The yellow zinc coating on these has held up well so far, no rust after a few weeks in a slightly damp workshop. They're fully threaded, which made it easy to get the exact grip I needed on a jig assembly.

These bolts threaded perfectly into my equipment without any binding, and the yellow zinc finish looks clean and professional. The hex heads hold up well under a socket wrench without stripping. Exactly what I needed for a solid assembly job.
