S-90594A028 1/4"-20 Weld Nuts

Key Features & Benefits at a Glance

• Superior welding stability with rectangular flange design that provides increased surface contact for secure, vibration-resistant joints in industrial assemblies
• Exceptional thread reliability through Class 1B thread fit that accommodates minor variations while maintaining consistent fastening performance
• Optimized barrel dimensions (5/16" diameter × 7/8" height) offering deep engagement for enhanced load distribution and structural integrity
• Robust steel construction ensuring high tensile strength and durability under demanding thermal and mechanical stress conditions
• Industry-standard compatibility with 1/4"-20 UNC coarse threads for seamless integration with existing equipment and components
• Right-hand thread orientation enabling intuitive installation and removal while preventing accidental loosening during operation
• Regulatory compliance assurance meeting REACH and RoHS 3 environmental standards for safe use across global manufacturing applications

Professional Applications & Engineering Value

This rectangular weld nut delivers critical solutions for permanent fastening in structural frameworks, machinery bases, and heavy-duty equipment where vibration resistance is paramount. The steel construction maintains integrity under repeated thermal cycling during welding processes, while the UNC coarse thread design prevents cross-threading in high-volume assembly operations. The extended 7/8" barrel height provides exceptional thread engagement depth, distributing shear loads across wider areas to prevent joint failure in industrial applications involving dynamic stresses. The rectangular flange profile increases weld surface area by approximately 40% compared to standard nuts, creating permanent connections that withstand extreme operational demands in automotive, construction, and manufacturing environments.

Specification Summary & Compliance

Manufactured to precise inch measurement standards with Class 1B thread fit tolerances ensuring reliable engagement with mating components. The UNC coarse thread (1/4"-20) follows established industrial specifications for consistent performance across applications. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations guarantees environmental safety and global market acceptance. Dimensions include 5/16" barrel diameter, 7/8" barrel height, and rectangular base measuring 3/4"×1/2"×1/16" for standardized integration into welding assemblies.
