1-8 UNC-2B Coupling Nut

1-8 UNC-2B Coupling Nut with both right-hand & left-hand threads, a unique design feature that makes this part stand out. Machined from Nitronic 60 for exceptional durability and wear resistance.

Nuts are machined from bar or hex stock, tapped to the thread class specified, and heat treated where the grade requires it. Heavy hex, jam, castellated, cap, seal and coupling patterns are turned in-house, so special dimensions cost no more than standard ones.

About the material: Nitronic 60 bolting — the anti-galling stainless: 95 ksi, non-magnetic, and threads that will not seize against other stainless steels. Read the A193 B8S data page →
