• Enhanced pull-out resistance thanks to the 0.211" flange diameter, distributing load over a wider surface area
• Optimized for high-speed assembly featuring coarse UNC threads and right-hand direction for efficient driving
• Simplified installation process with compatible 3/16" drill bit size, reducing preparation time and tooling requirements
• Environmentally compliant manufacturing meeting both REACH and RoHS 3 standards for responsible sourcing

Professional Applications & Engineering Value

This 4-40 UNC rivet nut delivers critical engineering solutions for metal assembly applications where reliable threaded anchors are essential. The tin-plated 18-8 stainless steel construction provides superior corrosion resistance, extending service life in demanding environments while the coarse thread spacing ensures rapid installation without cross-threading risks. The sleeve-type body design creates a permanent, vibration-resistant fastener in materials as thin as 0.030", solving common challenges in sheet metal fabrication, electronic enclosures, and automotive components. With its 0.187" body diameter and open end configuration, this rivet nut accommodates various mounting scenarios while maintaining consistent Class 2B thread fit for secure bolt retention.

Specification Summary & Compliance

This rivet nut maintains precision Class 2B thread fit per UNC standards with 4-40 coarse thread specification and right-hand thread direction. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives. Critical dimensions include 0.187" body diameter, 0.211" flange diameter, and installed length of 0.175" for material thickness range of 0.030" to 0.090". Compatible with standard 3/16" (0.1875") drill bits for simplified installation.
