براغي رأس سداسية 5/16-24 × 3 بوصة | فولاذ درجة 5 أصفر زنك | ملولبة جزئياً (100/عبوة)

These Grade 5 hex heads seated perfectly in my equipment’s socket drive without stripping, and the yellow zinc finish looks clean. The 3-inch length gave just enough thread engagement for my assembly job.

The partial threading made these perfect for my shop press frame where I needed a smooth shoulder to bear against the plate. They seated cleanly with a socket and the yellow zinc finish looks exactly like the original fasteners.

I needed these for a tractor linkage rebuild, and the grade 5 strength with the yellow zinc coating is holding up well so far. The partial threading made alignment a lot easier than fully threaded bolts would have.
