براغي رأس سداسية 5/8-18 × 2-1/4 بوصة | درجة 5 فولاذ أصفر زنك | ملولبة جزئياً (25 / عبوة)

These bolts threaded perfectly into my tractor's drawbar hitch without any binding, and the yellow zinc finish should resist rust well out in the weather. The partially threaded shank gave me the grip I needed without extra threads sticking out.

Threaded these into a tractor hitch bracket and the yellow zinc coating slid smoothly without any binding. The partial threading gave me just the right grip depth for a secure assembly.

Just installed these on a piece of heavy machinery and the partially threaded design made seating the bolt much easier than fully threaded ones. The yellow zinc finish seems like it will hold up well against occasional moisture.
