Professional Applications & Engineering Value

This nickel-plated brass cap nut delivers exceptional performance in demanding industrial applications where both corrosion resistance and reliable sealing are critical. The combination of brass material and nickel plating creates a robust barrier against oxidation and chemical degradation, making these UNC coarse thread fasteners ideal for plumbing systems, marine equipment, and electrical enclosures. The external hex drive configuration allows for high-torque installation without compromising the nut's structural integrity, while the standard cap nut profile effectively seals thread ends against moisture, dust, and other contaminants that could compromise assembly longevity.

Specification Summary & Compliance

This 5/16"-18 UNC cap nut features Class 2B thread fit per ASME B1.1 standards, ensuring dimensional accuracy and interchangeability. The coarse thread spacing (18 TPI) and right-hand thread direction comply with unified thread specifications. Manufacturing follows industry standards for nickel-plated brass fasteners, with precise dimensions including 9/16" width across flats and 7/16" total height. Components meet RoHS and REACH compliance requirements for industrial use.
