براغي سداسية ثقيلة 3/4-10 × 4-3/4 بوصة | ASTM A193 B7 سبيكة فولاذية عادية | ملولبة جزئيًا (55 / عبوة)

I bought these for a pump rebuild on a bucket truck, and the partially threaded shank grabbed perfectly in the blind hole without bottoming out early. The hex head took a socket wrench without any wobble or rounding. No complaints at all.

The threading is clean and the alloy steel feels solid—these bolts seated perfectly into my equipment mounts without any binding. The partially threaded length gave me just enough grip for the heavy flange I was securing.

The partial threading on these cap screws gives just the right grip depth for my equipment assembly, and the alloy steel feels solid without any flex. I used several to mount a motor bracket, and they torqued down smoothly without stripping.
