S-93031A158 10-32 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Reliable reverse-threading performance with left-hand thread direction for specialized mechanical assemblies requiring counter-clockwise tightening
• Precise thread engagement through Class 2B fine thread fit, ensuring secure fastening and vibration resistance
• Space-saving thin profile (7/64" height) for applications with limited clearance without compromising strength
• Standardized UNF fine threading (10-32) provides superior load distribution compared to coarse threads
• Easy installation and removal with external hex drive design compatible with common wrench tools
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally conscious manufacturing

Professional Applications & Engineering Value

This 10-32 UNF left hand thin hex nut in 316 stainless steel addresses critical engineering challenges in industries where standard right-hand threads would loosen under specific rotational forces. The Class 2B thread fit and fine thread spacing deliver exceptional vibration resistance in high-speed machinery, while the thin hex profile enables installation in confined spaces where standard nuts cannot fit. The left-hand thread direction is essential for safety-critical applications like rotating shaft assemblies, mixing equipment, and automotive systems where reverse rotation occurs. Combined with 316 stainless steel's superior corrosion resistance, this nut maintains integrity in marine, chemical processing, and food industry applications where moisture and corrosive agents are present.

Specification Summary & Compliance

This inch-system hex nut features precise 10-32 UNF fine threads with Class 2B thread fit tolerances, manufactured to standard inch dimensions (3/8" width, 7/64" height). The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance. The external hex drive design follows industry-standard tool compatibility requirements for reliable installation and maintenance.
