S-95355A235 3/8"-24 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments including marine and chemical applications
• Reliable reverse-thread security through left-hand threading, preventing loosening in counter-rotating machinery and equipment
• Precise fine thread engagement with UNF 3/8"-24 specification, delivering enhanced vibration resistance and load distribution
• Consistent thread quality with Class 2B fit ensuring smooth assembly and reduced risk of cross-threading during installation
• Standard external hex design provides familiar, tool-friendly installation with common wrenches for maintenance efficiency
• Environmental compliance assurance with RoHS 3 (2015/863/EU) certification for restricted substance control
• Optimized dimensional stability with 9/16" width and 21/64" height maintaining consistent performance under thermal and mechanical stress

Professional Applications & Engineering Value

This 316 stainless steel left-hand thread hex nut delivers critical performance where standard right-hand threads would compromise safety. The UNF fine threading (3/8"-24) creates more thread contact points than coarse threads, significantly improving fatigue resistance in high-vibration environments like rotating machinery, conveyor systems, and automotive assemblies. The Class 2B thread fit ensures consistent engagement without binding, while the external hex drive allows for high-torque installation with standard tools. Manufactured from 316 stainless steel, these nuts maintain integrity in corrosive applications including marine hardware, chemical processing equipment, and food processing machinery where moisture and chemicals would degrade inferior materials.

Specification Summary & Compliance

This left-hand thread hex nut features 3/8"-24 UNF fine threading with Class 2B thread fit per ASME/ANSI standards, ensuring precise dimensional accuracy. The standard external hex profile measures 9/16" across flats with 21/64" height. Manufacturing complies with RoHS 3 (2015/863/EU) requirements for hazardous substance restriction, making it suitable for regulated industries and international supply chains.
