S-90475A150 5/8"-11 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating, extending service life in demanding industrial environments
• Superior thread engagement through Class 2B thread fit, ensuring reliable fastening with minimal risk of cross-threading
• Space-saving thin profile (3/8" height) ideal for applications with limited clearance while maintaining full strength
• Quick installation efficiency with coarse UNC threading that accelerates assembly and reduces labor time
• Secure external hex drive provides excellent torque transmission and prevents tool slippage during tightening
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial supply chain requirements
• Optimized weight-to-strength ratio through precision engineering of thin hex nut design without compromising durability

Professional Applications & Engineering Value

This 5/8"-11 UNC thin hex nut delivers critical engineering advantages for industrial assembly applications where space constraints and corrosion resistance are primary concerns. The black-oxide steel construction provides superior protection against rust and oxidation in harsh environments, while the thin hex nut profile enables installation in tight spaces where standard nuts cannot fit. The coarse UNC threading with Class 2B thread fit ensures rapid assembly with reduced risk of cross-threading, making it ideal for high-volume production environments. These external hex drive fasteners are engineered for heavy machinery, structural frameworks, and automotive applications where vibration resistance and long-term reliability are essential. The right-hand thread design provides standard installation compatibility across industrial equipment maintenance and manufacturing operations.

Specification Summary & Compliance

This hex nut features precise Class 2B thread fit tolerance according to UNC standards with 5/8"-11 coarse thread spacing. Dimensions include 15/16" width across flats and 3/8" height for the thin profile configuration. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial fastener applications. The product meets standard industrial specifications for black-oxide steel fasteners with external hex drive and right-hand thread orientation.
