S-98560A527 4-40 x 0.37" Rivet Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with tin-zinc plating, extending service life in harsh industrial environments.
• Reliable, high-strength fastening in metal sheets from 0.03" to 0.09" thickness, preventing pull-through and loosening.
• Easy and quick installation using a standard 3/16" drill bit, reducing assembly time and labor costs.
• Secure Class 2B thread fit ensures consistent engagement with 4-40 UNC coarse threaded bolts, minimizing cross-threading risks.
• Wide flange design (0.211" diameter) distributes load effectively, enhancing joint integrity in dynamic applications.
• Open end and right-hand thread allow for versatile, straightforward installation from one side of the workpiece.
• Compliance with REACH and RoHS 3 guarantees environmental and safety standards for global supply chain integration.

Professional Applications & Engineering Value

This 4-40 UNC coarse thread rivet nut is engineered for robust performance in metal fabrication, automotive assemblies, and machinery where reliable blind fastening is critical. The tin-zinc plated steel construction provides excellent resistance to oxidation and galvanic corrosion, addressing common failure points in exposed or high-moisture environments. Its sleeve design and 0.187" body diameter enable secure installation in pre-drilled holes, while the coarse thread ensures quick engagement and vibration resistance. Ideal for applications requiring repeated disassembly, this rivet nut solves the challenge of creating strong, reusable threads in thin metal sheets without backside access, streamlining production and maintenance processes.

Specification Summary & Compliance

This rivet nut adheres to UNC coarse thread standards with a Class 2B thread fit for consistent dimensional accuracy. Key specifications include a body diameter of 0.187", flange diameter of 0.211", and installed length of 0.205". It is designed for material thicknesses from 0.03" to 0.09" and requires a 3/16" drill bit for installation. The product is manufactured in compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, ensuring it meets stringent environmental and safety regulations for industrial use.
