S-90596A280 3/8"-16 Weld Nuts

Key Features & Benefits at a Glance

• Secure welding integration with a 1" base diameter and 1/16" thickness for stable, distortion-resistant attachment to metal surfaces
• Reliable coarse thread performance using 3/8"-16 UNC threads that resist cross-threading and enable quick assembly in high-vibration environments
• Optimized barrel design with 0.44" diameter and 5/8" height provides consistent weld penetration and alignment during installation
• Class 1B thread fit tolerance ensures smooth mating with corresponding male threads while maintaining secure fastening integrity
• Durable steel construction delivers consistent strength and corrosion resistance for long-term industrial service life
• Right-hand thread orientation enables standard installation procedures compatible with common assembly tools and techniques
• Environmental compliance assurance with RoHS 3 and REACH standards for use in regulated manufacturing applications

Professional Applications & Engineering Value

This round steel weld nut addresses critical challenges in industrial welding applications where thread integrity and installation reliability are paramount. The UNC coarse thread configuration prevents binding during high-speed assembly operations while maintaining vibration resistance in machinery, automotive frames, and structural steel applications. The standard barrel profile and precise 1" base diameter ensure consistent weld pool formation without burn-through, making it ideal for automated welding systems. Engineers specify this Class 1B thread fit weld nut for applications requiring repeated disassembly and reassembly, as the slightly looser tolerance facilitates maintenance access while maintaining secure fastening performance in demanding environments.

Specification Summary & Compliance

This weld nut maintains UNC coarse thread standards with Class 1B thread fit tolerances according to established industrial specifications. The dimensional configuration includes a 0.44" barrel diameter, 5/8" barrel height, and 1" base diameter with 1/16" thickness for consistent welding performance. The product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations regarding chemical safety, ensuring suitability for global industrial supply chains and regulated manufacturing environments.
