3.250"-8 UN-2B heavy hex nut manufactured from ASTM A194 Grade 8 stainless steel, precision-machined to customer drawing.
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: 304 stainless heavy hex nut for A193 and A320 B8 studs — solution treated, 80 ksi proof load, corrosion resistant from cryogenic to 1500 °F. Read the A194 8 data page →
