S-90083A205 1/4"-28 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced torque transmission through external hex drive design for secure tightening in confined spaces
• Reliable reverse-thread security with left-hand UNF threads preventing loosening in counter-rotating applications
• Precision thread engagement with Class 2B fine threads ensuring vibration-resistant connections
• Space-saving profile with thin hex design ideal for weight-sensitive assemblies
• Industrial-grade durability from Grade 2 steel construction supporting standard load applications
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global supply chain integration
• Optimized dimensional compatibility with 7/16" width and 5/32" height for standardized tooling

Professional Applications & Engineering Value

This left-hand thin hex nut addresses critical challenges in rotating machinery and specialized equipment where standard right-hand threads would naturally loosen. The Grade 2 steel construction provides balanced strength-to-weight ratio for applications requiring repeated disassembly, while the UNF fine threads (1/4"-28) deliver superior resistance to vibrational loosening in automotive, aerospace, and industrial machinery. The external hex drive enables efficient torque application even in limited clearance environments, making these thin hex nuts particularly valuable for compact assemblies. Engineered with Class 2B thread fit, these components ensure consistent engagement with mating fasteners, reducing installation time and improving assembly reliability across production lines.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 7/16" width and 5/32" height, this hex nut maintains Class 2B thread tolerances per UNF specifications. The component fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while meeting Grade 2 strength requirements for reliable performance in industrial fastening applications.
