S-95195A140 5/16"-18 Hex Nuts

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Reliable left-hand threading prevents unintended loosening in counter-clockwise rotating applications
• Precise Class 2B thread fit ensures smooth assembly and consistent clamping force
• Coarse UNC threading provides faster installation and reduced cross-threading risks
• Standard external hex drive enables easy installation with common wrench tools
• Full regulatory compliance with RoHS 3 and REACH standards for global industrial use
• Durable standard profile with 1/2" width and 17/64" height for consistent performance

Professional Applications & Engineering Value

This 5/16"-18 left hand UNC hex nut delivers critical reverse-threading security for industrial machinery, automotive systems, and rotating equipment where standard right-hand threads would naturally loosen. The 18-8 stainless steel composition provides exceptional corrosion resistance, making these industrial hex nuts suitable for outdoor applications, marine environments, and chemical processing facilities. The coarse thread spacing combined with Class 2B thread fit ensures rapid assembly while maintaining vibration resistance, reducing installation time and maintenance costs. These left hand thread hex nuts are engineered to prevent accidental disassembly in counter-clockwise rotating systems, providing essential safety in power transmission, conveyor systems, and specialized manufacturing equipment.

Specification Summary & Compliance

This external hex drive nut features 5/16"-18 UNC coarse threads with Class 2B thread fit for consistent dimensional accuracy. The standard hex nut profile measures 1/2" across flats with 17/64" height. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability for industrial procurement requirements.
