S-90186A313 1/4"-20 x 0.902" Rivet Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance with 4-sided bulbed design that creates multiple contact points for enhanced grip in metal substrates
• Exceptional corrosion protection through zinc-plated steel construction, extending service life in demanding industrial environments
• Optimized load distribution from the 0.63" flange diameter, preventing pull-through and maintaining joint integrity under stress
• Quick installation compatibility with standard 7/16" drill bits, reducing assembly time and tooling requirements
• Versatile material thickness accommodation ranging from 0.188" to 0.375", providing flexibility across various metal applications
• Reliable coarse thread engagement with 1/4"-20 UNC threads ensuring secure fastening even in vibration-prone applications
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use without environmental restrictions

Professional Applications & Engineering Value

This zinc-plated steel rivet nut delivers critical engineering solutions for metal applications where traditional fastening methods fall short. The bulbed design with four folding sides creates radial expansion upon installation, forming a permanent threaded insert that withstands vibration and dynamic loads far better than standard fasteners. The UNC coarse thread pattern ensures rapid assembly while maintaining exceptional pull-out strength, making it ideal for automotive frames, machinery enclosures, and structural metal fabrications. Engineered specifically for material thicknesses from 0.188" to 0.375", this rivet nut eliminates the need for welded inserts or through-bolting, significantly reducing installation time while providing reliable threaded inserts in blind applications where only one-side access is available.

Specification Summary & Compliance

This 1/4"-20 UNC rivet nut features precise dimensional specifications including 0.472" body diameter, 0.63" flange diameter, and 0.902" length with Class 2A thread tolerances. Manufactured to industrial standards for metal rivet nuts, the product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while maintaining the mechanical properties required for demanding industrial applications.
