S-93031A189 1 1/4"-12 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance in harsh environments thanks to 316 stainless steel construction
• Secure, fine-threaded connections with precise Class 2B thread fit for reduced vibration loosening
• Space-saving thin profile design ideal for applications with limited clearance
• Reliable left-hand threading for specialized assemblies requiring reverse rotation security
• Easy installation and removal with standard external hex drive compatibility
• Full regulatory compliance with RoHS 3 and REACH standards for global industrial use
• Durable inch-system compatibility ensuring interchangeability with UNF fine-threaded components

Professional Applications & Engineering Value

This left hand thin hex nut delivers critical engineering solutions where standard fasteners fail. The 316 stainless steel material provides superior resistance to chemicals, saltwater, and extreme temperatures, making it ideal for marine, chemical processing, and food industry applications. Its UNF fine thread design maintains clamping force under high-vibration conditions, while the left-hand thread direction prevents accidental loosening in rotating machinery. The thin hex profile allows installation in confined spaces without compromising strength, and the external hex drive ensures compatibility with standard wrenching tools for efficient maintenance.

Specification Summary & Compliance
