براغي رأس سداسية 7/8-9 × 3-1/4 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئياً (15 / عبوة)

These bolts threaded in cleanly with a wrench, no binding at all. The partial threading gave me just the right grip for the bracket I was mounting, and all fifteen heads seated flush.

I needed some heavy-duty bolts for a repair on my tractor's PTO shaft, and these grade 5 cap screws fit perfectly. The yellow zinc coating looks like it will resist rust well, and the partial threading made installation easier.

These hex bolts came in a sturdy package of 15, and the yellow zinc coating looks consistent across every single one. The partial threading gave me just the right grip for a machine frame I’m rebuilding, no wobble once torqued down.
