S-3022T712 1/4"-20 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 Stainless Steel construction, ideal for marine and chemical applications
• Reliable left-hand thread engagement prevents loosening in counter-rotational systems, enhancing operational safety
• Precise Class 2B thread fit ensures smooth assembly and consistent clamping force, reducing installation time
• Robust UNC coarse threading provides excellent wear resistance and is less prone to cross-threading during high-speed assembly
• Standard external hex drive design offers compatibility with common tools for straightforward installation and removal
• Full regulatory compliance with RoHS 3 and REACH standards, ensuring material safety for global industrial supply chains
• Durable turnbuckle compatibility with 316 Stainless Steel material maintains structural integrity under tension and outdoor exposure

Professional Applications & Engineering Value

This 1/4"-20 UNC left-hand thread hex nut delivers critical performance where standard right-hand threads would compromise system integrity. Engineered from 316 Stainless Steel, it solves corrosion-related failure in marine hardware, chemical processing equipment, and coastal infrastructure. The coarse UNC thread spacing combined with Class 2B fit maintains reliable engagement in high-vibration environments like machinery and transportation systems. Its left-hand thread direction is essential for turnbuckles, mixer blades, and rotating assemblies where reverse-thread locking prevents accidental disassembly. The external hex drive profile ensures maximum torque transfer during installation, while the material's chromium-nickel-molybdenum composition provides pitting resistance beyond basic stainless grades.

Specification Summary & Compliance

This hex nut maintains Class 2B thread fit per Unified National Coarse (UNC) standards with dimensions of 1/4"-20 thread size, 7/16" width across flats, and 7/32" height. Manufacturing conforms to industry standards for left-hand thread fasteners and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations regarding hazardous substances. The 316 Stainless Steel material ensures consistent performance in corrosive environments while meeting mechanical requirements for industrial turnbuckle and structural applications.
