براغي رأس سداسية 1/2-20 × 5-1/2 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (25/عبوة)

The yellow zinc finish on these screws looks great and seems like it will hold up to corrosion better than some others I've used. They drove in smoothly with a socket, and the partial threading was exactly what I needed for a machinery jig I'm building.

The yellow zinc coating is a nice touch since it lets me spot these Grade 5s at a glance in my hardware bins, and the partial threading gave me just enough grip for the bracket I was mounting. Wrenched down tight with no stripping, and the 25-pack means I've got spares for the next job.

These bolts fit perfectly into my tractor’s drawbar mount, and the yellow zinc finish already looks like it’ll resist rust better than plain steel ones I’ve used before.
