براغي رأس سداسي 9/16-18 × 1-1/2 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة بالكامل (25/عبوة)

These threads cut clean and seated perfectly into the tapped hole on my press. The zinc coating looks uniform and the hex heads gave my wrench a solid grip. I'm glad I went with the Grade 5 for this application.

Used a socket on these for a repair job and they seated perfectly without any wobble. The yellow zinc finish held up well against my wrench, no stripping.

The threads are clean and the yellow zinc coating looks uniform across all 25 pieces, so they should hold up fine in my shop. I've used cheaper bolts before that stripped easily, but these Grade 5s felt solid tightening down a heavy jig.
