SS Hex Nut

Stainless steel hex nuts per ISO 4032 / DIN 934 are six-sided internally threaded fasteners designed to mate with bolts and threaded rods. Available in A2 (304) and A4 (316) grades, they provide removable threaded connections for structural, mechanical, and general engineering assemblies.

Dimension #

• All dimensions in mm, tolerance +/- 0.01 mm. Additional dimensions available on request.

Benefits #

Standard hex nuts are the most widely used nut type in bolted joint design, offering full thread engagement for maximum load transfer. The ISO 4032 regular height provides sufficient thread engagement to develop the full tensile strength of the mating bolt. Stainless steel A2 and A4 grades eliminate coating requirements in corrosive environments, from atmospheric exposure to marine and chemical service. The hexagonal geometry is compatible with standard wrenches, sockets, and power tools, enabling efficient installation and removal. For temperature-varying applications, stainless steel maintains mechanical properties from cryogenic to approximately 870°C. In hygienic environments such as food processing and pharmaceutical facilities, the smooth stainless surface resists contamination and supports cleaning protocols.

Common Applications #

Stainless steel hex nuts are used in virtually every industry requiring corrosion-resistant threaded connections.
