براغي رأس سداسي 1/2-13 × 2-3/4 بوصة | فولاذ درجة 2 مطلي بالزنك الأصفر | ملولبة جزئيًا (300 / عبوة)

The hex heads grabbed my socket wrench perfectly with zero stripping, and the yellow zinc coating looks clean and uniform across all 300 pieces. Threading into pre-tapped holes was smooth, and the partial thread gave me just the right grip for a tight machinery mount.

I just used these to bolt down a heavy motor mount, and the zinc coating looks clean and even across all 300 pieces. The hex heads grabbed my socket nicely without any stripping.

The partially threaded design on these 1/2-13 screws is exactly what I needed for a jig assembly where the thread had to stop short. The yellow zinc coating looks uniform across all 300 pieces, and the hex heads fit a standard wrench without any slop.
