2"-4.5 UNC-2B Heavy Hex Nut

2"-4.5 UNC-2B heavy hex nut made from domestic AISI 304 stainless steel for corrosion resistance and lasting performance in demanding applications.

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 general-purpose 18-8 stainless: 75 ksi annealed bar, cold-worked bolts to 160 ksi, non-magnetic, and resistant to water, food and most mild chemicals. Read the 304 Stainless data page →
