1-5/8"-6 Custom Nut

1-5/8"-6 nut manufactured to the customer's drawing in ASTM A194 Grade 6.

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: The 410 stainless heavy hex nut for A193 B6 studs — hardened and tempered, 20 to 28 HRC, for valve and steam service. Read the A194 6 data page →
