Professional Applications & Engineering Value

This zinc yellow-chromate-plated steel rivet nut delivers exceptional engineering value in plastic assembly applications where vibration resistance and long-term reliability are critical. The bulbed body design expands during installation to create a permanent, high-strength fastener that prevents pull-through in softer materials. With coarse UNC threading and Class 2B thread fit, this rivet nut ensures smooth installation while maintaining precise thread alignment. The four folding sides provide uniform expansion for consistent performance across various plastic thicknesses, making it ideal for automotive trim, electronic enclosures, and industrial equipment where plastic fastening solutions require both strength and corrosion protection.

Specification Summary & Compliance

This 5/16"-18 UNC rivet nut features precision Class 2B thread fit with coarse thread spacing and right-hand thread direction. The fastener maintains dimensional accuracy with 0.5" body diameter, 0.77" flange diameter, and 1.141" overall length. Manufacturing compliance includes full adherence to REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental safety and material quality standards. Designed for installation in materials ranging from 0.020" to 0.280" thickness using 1/2" drill bits, this rivet nut delivers consistent performance across industrial applications.
