SS Hex Nut (INCH)
Stainless steel hex nuts (inch series) per ASME B18.2.2 are six-sided internally threaded fasteners with UNC threads. Available in 304 and 316 grades, they provide removable threaded connections for inch-based structural, mechanical, and general engineering assemblies.

Benefits
#
Inch-series hex nuts serve the same engineering function as metric hex nuts but conform to ASME B18.2.2 dimensional standards and UNC thread specifications. They provide full thread engagement for maximum load transfer in inch-based bolted joints. The 304 and 316 stainless steel construction eliminates coating requirements in corrosive environments, including marine, chemical, and atmospheric exposure. UNC thread series nuts share identical body dimensions for a given nominal size, simplifying inventory management. The hexagonal geometry works with standard inch-based wrenches and sockets. Stainless steel maintains mechanical properties across a wide temperature range and meets hygienic requirements in food processing and pharmaceutical installations.
Common Applications
#
Inch-series stainless steel hex nuts are specified in applications using UNC threaded fasteners.
- Structural connections and frameworks (inch-based)
- Machinery and equipment assembly
- Automotive and vehicle components
- Marine and shipbuilding hardware
- Architectural and construction fastening
- Electrical enclosures and control panels
- HVAC and mechanical systems
- Piping and flange connections
- Agricultural and heavy equipment
