براغي رأس سداسية 5/8-11 × 5-1/2 بوصة | درجة 5 فولاذ أصفر زنك | ملولبة جزئيًا (70 / عبوة)

The yellow zinc finish looks great and held up fine during installation. I torqued them down on a jig frame and the grade 5 rating gives me confidence they won't let go under load.

These bolts threaded perfectly into my tractor's implement mounts, and the yellow zinc coating looks like it'll resist rust well. The partial threading made it easy to snug up against a thick bracket without binding. Exactly the heavy-duty grip I needed for attaching a new blade assembly.

Picked up a pack for my tractor’s lift arm pins and the partial threads made alignment a breeze. The heads are solid under torque, no rounding at all. Good value for the count.
