Professional Applications & Engineering Value

This zinc-plated steel rivet nut delivers exceptional engineering value in metal fabrication and assembly operations. The hex body design provides anti-rotation stability during installation, eliminating the common problem of fastener spin-out in thin metal sections. With its 5/16"-18 UNC coarse thread spacing, this fastener enables rapid installation while maintaining secure connections in sheet metal, enclosures, and structural components. The 0.562" flange diameter distributes clamping force effectively, preventing material deformation in applications ranging from 0.175" to 0.245" thickness. This combination of features makes it ideal for automotive, machinery, and electrical enclosure applications where reliable threaded fastening in metal substrates is critical for long-term performance and safety.

Specification Summary & Compliance

This heavy-duty rivet nut features precise Class 2B thread fit tolerances with 5/16"-18 UNC coarse thread specifications and right-hand thread direction. The fastener maintains dimensional accuracy with 0.368" body diameter, 3/8" width across flats, and 0.655" overall length. Manufacturing compliance includes full adherence to REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) environmental standards, ensuring suitability for global industrial applications requiring certified components.
