S-94430A444 1/4"-20 x 0.68" Rivet Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance with ribbed body design that prevents rotation during and after installation
• Lightweight corrosion resistance through aluminum construction ideal for metal applications without adding significant weight
• Reliable thread engagement with Class 2B thread fit ensuring consistent performance in coarse thread applications
• Enhanced load distribution from 1/2" flange diameter providing wider bearing surface for secure fastening
• Quick installation compatibility with standard 25/64" drill bits for efficient field assembly
• Environmental compliance assurance meeting both REACH and RoHS 3 standards for global industrial use
• Versatile material thickness accommodation designed for 0.165" to 0.260" metal sheets commonly used in manufacturing

Professional Applications & Engineering Value

This aluminum rivet nut solves critical challenges in metal fabrication and assembly operations where vibration resistance and weight reduction are paramount. The ribbed body design creates permanent anti-rotation characteristics that maintain fastener integrity in high-stress environments, while the 1/4"-20 UNC coarse threading provides excellent engagement in thinner metal sections (0.165"-0.260" thickness range). Engineers specify this right-hand thread rivet nut for applications requiring repeated disassembly and reassembly, as the open end design accommodates through-bolting without thread damage. The combination of aluminum material and industrial-grade construction makes it ideal for automotive, electronics, and machinery applications where corrosion resistance and structural integrity must coexist.

Specification Summary & Compliance

This rivet nut maintains Class 2B thread fit tolerance per UNC standards, ensuring reliable engagement with mating components. The product conforms to REACH (EC 1907/2006) regulations regarding substance restrictions and RoHS 3 (2015/863/EU) directives for hazardous materials limitation. Manufacturing specifications include 0.39" body diameter, 1/2" flange diameter, and 0.68" total length with UNC coarse thread spacing optimized for rapid installation in metal substrates using standard 25/64" drill preparation.
