Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade 2H hex nut addresses critical challenges in machinery, structural assemblies, and equipment manufacturing. The zinc yellow-chromate plated steel construction delivers superior corrosion resistance, preventing fastener failure in moist or chemically aggressive environments. Its extra wide profile and external hex drive enable higher torque application and secure fastening, reducing the risk of stripping during installation. The 5/16"-18 UNC coarse thread ensures quick assembly and reliable performance in high-vibration settings, while the Class 2B thread fit maintains precision for consistent joint integrity. Ideal for construction, automotive, and heavy equipment sectors where durability and compliance with ASME B18.2.2 are paramount.
Specification Summary & Compliance
This hex nut features precise Class 2B thread fit per UNC standards, with dimensions of 9/16" width and 19/64" height. It conforms to ASME B18.2.2 for dimensional accuracy and ASTM A194 for material specifications, ensuring reliable performance in industrial fastening. The zinc yellow-chromate plating provides environmental protection, and the nut meets common industry requirements for heavy-duty applications, though specific RoHS or REACH compliance should be verified per batch.
