3/4-10 × 5-1/4" براغي ذات رأس سداسي ثقيل | سبيكة فولاذية ASTM A193 B7 عادية | ملولبة جزئياً (50/عبوة)

Needed a dozen for a flanged coupling repair and the threads cut cleanly into the tapped hole without any galling. The heavy hex head gave my socket a solid bite, and the partial thread left plenty of grip length.

Installed these on a heavy press fixture and the partially threaded design made alignment much easier than fully threaded bolts. The hex head gave me great grip with a standard socket.

The threads on these bolts are surprisingly clean and sharp, so they started smoothly without any galling. I used them to secure a heavy press and the partially threaded shank gave just the right grip length.
