براغي رأس سداسية ثقيلة 1-8 × 4-3/4 بوصة | سبيكة فولاذ ASTM A193 B7 عادي | جزئية الخيوط (30 / عبوة)

Needed heavy-duty bolts for a press rebuild and these threaded perfectly into Grade 8 nuts without any galling. The plain finish still had a nice, even coating of oil right out of the package.

The partially threaded design made alignment a breeze on my press setup, and the B7 alloy threading cut cleanly without galling. These hex heads seated flush with a standard socket, and all 30 pieces showed consistent plating and thread form right out of the pack.

I needed a heavy-duty bolt for a steel beam repair and these hex cap screws threaded in smoothly with no binding. The 4-3/4" length and partial threading gave me just the right grip depth for my application.
