S-95195A170 3/8"-24 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and reducing maintenance costs.
• Reliable reverse-thread security with left-hand thread direction, preventing loosening in applications with counter-clockwise rotational forces.
• Precise and secure fastening ensured by the Class 2B thread fit, offering superior engagement and vibration resistance.
• Optimized for fine-adjustment applications due to the UNF fine thread spacing, providing greater clamping force and load distribution.
• Easy installation and removal with a standard external hex drive profile, compatible with common wrenches for efficient assembly.
• Compliance with stringent environmental regulations, being RoHS 3 and REACH compliant for safe use in regulated industries.
• Durable and long-lasting performance from a standard hex nut profile, ensuring consistent reliability in demanding mechanical assemblies.

Professional Applications & Engineering Value

This 3/8"-24 UNF left hand thread hex nut is engineered to solve critical challenges in industrial settings where standard right-hand threads may loosen under specific rotational stresses. Crafted from 18-8 stainless steel, it provides excellent resistance to corrosion and oxidation, making it suitable for marine, chemical processing, and outdoor equipment. The fine thread spacing and Class 2B thread fit deliver a tighter, more secure connection, minimizing the risk of vibration-induced failure in machinery, automotive, and aerospace assemblies. Its external hex drive allows for high-torque application with standard tools, streamlining maintenance and reducing downtime. This nut is a reliable choice for applications requiring reverse-thread security and long-term durability in corrosive environments.

Specification Summary & Compliance

This hex nut adheres to UNF (Unified National Fine) thread standards with a Class 2B thread fit for consistent dimensional accuracy. The specifications include a 3/8"-24 left-hand thread, a width of 9/16", and a height of 21/64". It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use.
