3/4-10 × 9" براغي رأس سداسي | درجة 5 فولاذ أصفر زنك | ملولبة جزئيًا (30/عبوة)

Picked up a pack of these for a heavy-duty repair on a press machine, and the partially threaded design made alignment much easier than fully threaded bolts. They drive in smoothly with a socket and hold tight under load.

The yellow zinc coating on these bolts is consistent and clean, no flaking or rough edges at all. I’ve been using them to fasten a large gearbox and the 3/4-10 threads threaded smoothly through the steel plate without any binding.

I needed these for a heavy-duty equipment repair, and the grade 5 steel with yellow zinc held up perfectly under torque. The partial threading made alignment much easier than my usual fully threaded bolts.
