S-98280A410 1/4"-20 x 1.19" Rivet Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc yellow-chromate plating for extended service life in harsh industrial environments
• Exceptional vibration resistance thanks to the ribbed body design that prevents rotation during and after installation
• Reliable, coarse-thread performance with 1/4"-20 UNC Class 2B thread fit ensuring easy starting and robust fastening in metal
• Versatile installation range accommodating material thicknesses from 0.027" to 0.165" for broad application flexibility
• Secure, closed-end sealing that prevents moisture and debris ingress, protecting internal threads and assemblies
• Streamlined assembly process with compatibility for standard 25/64" drill bits, reducing preparation time and tooling costs
• Compliance with global standards including REACH and RoHS 3, ensuring safety and environmental responsibility in your supply chain

Professional Applications & Engineering Value

This heavy-duty rivet nut is engineered to solve critical challenges in metal assembly applications where vibration resistance and long-term reliability are paramount. The ribbed body design bites securely into parent material, eliminating spin-out during torque application—a common failure point in dynamic load environments. Manufactured from zinc yellow-chromate-plated steel, it provides excellent corrosion resistance for outdoor equipment, automotive frames, and machinery exposed to industrial atmospheres. The closed end type offers superior sealing in fluid-handling systems or electrical enclosures, while the coarse UNC thread spacing ensures rapid installation and high pull-out strength in sheet metal, extrusions, and structural components. This combination of features delivers reduced maintenance cycles and enhanced structural integrity for OEMs and MRO operations.
