براغي رأس سداسي مقاس 7/8-9 × 10 بوصة من الفولاذ درجة 5 مع طلاء زنك أصفر ملولبة جزئيًا (10/عبوة)

Put these in a heavy-duty bracket assembly yesterday and the Grade 5 steel held torque perfectly without stripping. The partially threaded design made spacing the bolt exactly where I needed it.

Threads chased cleanly onto a 7/8-9 nut with no binding, and the yellow zinc coating held up fine under my wrench. For a ten-pack of this size, the price felt fair, and the hex head gave plenty of grip for torquing down.

Just finished assembling a large press frame and these cap screws threaded in smoothly without any binding. The yellow zinc coating looks consistent and the partial thread made alignment much easier.
