Materials and Finishes

Structural and Heavy Hex Nuts come in grades matched to the load, from carbon steel through high-strength alloy and corrosion-resistant stainless, with finishes from plain and zinc through hot-dip galvanized for outdoor and washdown service. Pair them with bolts, environmental, and Flat Washers to round out the assembly.

How to Choose

Size it first with diameter, thread pitch, and length. From there, pick the grade that handles the load and a finish that matches where it will live, moving to alloy or stainless for high-stress or wet conditions.
