S-95355A231 3/8"-16 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from 316 stainless steel construction, ideal for harsh marine and chemical environments
• Reliable left-hand thread security prevents loosening in counter-clockwise rotating applications
• Precise Class 2B thread fit ensures smooth assembly and consistent clamping force
• Standard UNC coarse threading provides faster installation and better debris clearance
• External hex drive design allows for high-torque application with common tools
• RoHS 3 compliance meets environmental safety standards for restricted substances
• Durable standard profile maintains structural integrity under repeated use

Professional Applications & Engineering Value

This 316 stainless steel left-hand hex nut delivers critical performance where standard right-hand threads would loosen under counter-clockwise rotation. The UNC coarse thread design enables rapid installation in industrial equipment, marine hardware, and chemical processing systems while providing superior resistance to cross-threading. Class 2B thread fit guarantees consistent engagement with mating components, reducing assembly time and preventing galling. The external hex drive accommodates standard wrenches for secure tightening in confined spaces. Engineered for demanding applications where corrosion resistance and reverse-thread reliability are essential, this nut maintains integrity in saltwater exposure, chemical splashes, and high-humidity environments where ordinary fasteners would fail prematurely.

Specification Summary & Compliance

This left-hand hex nut features 3/8"-16 UNC coarse threading with Class 2B thread fit tolerance for precise mating. Manufactured from 316 stainless steel with standard external hex drive (9/16" width, 21/64" height). Compliant with RoHS 3 (2015/863/EU) environmental standards for restricted substances. Thread specifications conform to Unified National Coarse standards for industrial applications requiring left-hand thread security.
