2-3/4"-8 UN-3B special heavy hex nut, drilled and beveled per drawing, machined from ASTM A193 B7 alloy steel for critical bolted joints.
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 workhorse alloy-steel bolting grade for flanges, valves and pressure equipment — 125 ksi tensile, quenched and tempered 4140. Read the A193 B7 data page →
