3/4-10 UNC-2B Heavy Hex Nut

3/4-10 UNC-2B Heavy Hex Nut Silicon Bronze 655-H04 Hard Manufactured for strength, durability, and dependable performance. When reliability matters, every detail counts.

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 strongest common silicon bronze in bar form, 90 ksi in hard temper and 100 ksi extra-hard in small rod — for machined marine fasteners, valve stems and pump parts. Read the C65500 Silicon Bronze data page →
