براغي رأس سداسي 7/16-14 × 3-1/4 بوصة | درجة 5 فولاذ مطلي بالزنك الأصفر | ملولبة جزئيًا (50/عبوة)

The partially threaded design made these perfect for tightening a few pieces of farm equipment where I needed a firm seat without the shank binding up. They drove in smoothly with my socket wrench and the yellow zinc finish already looks like it'll resist rust well.

Used these to bolt down a heavy motor mount and the zinc yellow coating is holding up nicely against shop grime. The hex heads grabbed a socket cleanly without rounding off, and the partial threads let me get a solid bite without bottoming out. Exactly what I needed for a solid 50-pack price.

The partially threaded design made these easy to start by hand before tightening with a socket—perfect for my shop press rebuild.
