S-90083A210 5/16"-24 Hex Nuts

Key Features & Benefits at a Glance

• Left-hand thread design provides secure fastening in applications requiring reverse rotation resistance, preventing accidental loosening under counter-clockwise motion.
• Low-profile 3/16" height offers space-saving advantages in compact assemblies without compromising structural integrity.
• Class 2B thread fit ensures smooth, precise engagement with mating components, reducing assembly time and minimizing cross-threading risks.
• Grade 2 steel construction delivers reliable strength and durability for general industrial use, balancing cost-efficiency with performance.
• Fine UNF thread spacing (24 TPI) enhances vibration resistance and allows for finer adjustment in precision machinery applications.
• External hex drive enables quick installation and removal with standard wrenching tools, improving maintenance efficiency.
• RoHS 3 and REACH compliance guarantees environmental safety and regulatory adherence for global supply chain integration.

Professional Applications & Engineering Value

This left-hand thread thin hex nut addresses critical engineering challenges in rotating machinery and specialized equipment where reverse-direction forces are prevalent. The Grade 2 steel composition provides optimal strength-to-weight ratio for applications requiring repeated disassembly, while the fine UNF threads maintain clamping force under high-vibration conditions commonly found in automotive, aerospace, and industrial manufacturing. The low-profile design is particularly valuable in confined spaces where standard nuts would interfere with adjacent components, making it ideal for electronic enclosures, conveyor systems, and precision instrument assembly. With its Class 2B thread fit, this fastener ensures consistent performance in automated production environments where threading accuracy directly impacts throughput quality.

Specification Summary & Compliance

This hex nut maintains Class 2B thread tolerances per UNF standards with precise 5/16"-24 fine threading. Manufacturing conforms to standard industrial specifications for Grade 2 steel fasteners, featuring 1/2" width across flats and 3/16" height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current substance restriction requirements for international industrial applications.
