براغي رأس سداسي مقاس 1/2-13 × 5-1/2 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة جزئيًا (100 / عبوة)

These bolts worked perfectly for a heavy equipment frame I was repairing. The hex heads let me get good torque with my socket, and the yellow zinc coating seems tough enough to resist rust.

Used these to bolt a new motor mount to the frame, and the partially threaded design made seating everything much easier than I expected. All 100 came with the hex heads clean and the yellow zinc coating uniform, no stripped threads or burrs in the box.

The yellow zinc finish looks great and the grade 5 rating gives me confidence for my machinery jigs. The partial threading makes alignment a lot easier than wrestling with fully threaded bolts, and the hex head grabbed cleanly with my socket.
