Hex nuts are widely used industrial fasteners designed for removable joints with bolts, studs and threaded rods. Products in this category can be selected by standard, thread diameter, pitch, nut dimensions, property class, material and surface finish.
Hex Nut Selection Guide
Begin by matching the nut standard and thread size with the corresponding bolt or stud. Then confirm the property class, thread series, material and finish according to the required load and service environment.
Standards: ASME, ASTM, DIN and ISO
Thread series: Metric, UNC, UNF and other specified series
Materials: Carbon steel, alloy steel and stainless steel
Finishes: Plain, zinc plated, hot-dip galvanized and other industrial coatings
Technical data: Width across flats, nut thickness, thread pitch, theoretical mass and grade
Select the required standard and size to view exact dimensional data, theoretical mass and product specifications. Final pricing depends on mass, material, grade, finish and order quantity.
