S-95878A310 5/16"-18 Locknuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction for extended service life in harsh environments
• Reliable vibration resistance through center lock distorted thread technology that maintains clamp force under dynamic loads
• Easy installation and removal with standard external hex drive and UNC coarse threading for efficient assembly
• Consistent thread engagement with Class 2B fit ensuring proper mating with male threads
• Environmental compliance assurance meeting RoHS 3 and REACH standards for regulated applications
• Dimensional stability with precise 1/2" width and 17/64" height for uniform performance across installations
• Heavy-duty locking performance through distorted thread design that eliminates the need for additional locking components

Professional Applications & Engineering Value

This 316 stainless steel locknut delivers exceptional engineering value through its center lock distorted thread technology, specifically engineered to address vibration-induced loosening in demanding industrial environments. The UNC coarse thread profile ensures rapid installation while maintaining secure fastening in applications subject to constant motion or thermal cycling. Manufactured from premium 316 stainless steel, this locknut provides superior corrosion resistance in chemical processing, marine, and food processing equipment where moisture and corrosive agents are present. The external hex drive allows for standard tool engagement, streamlining maintenance procedures while the distorted thread locking mechanism creates consistent friction along the thread engagement surface, eliminating the need for secondary locking devices and reducing assembly time in production environments.

Specification Summary & Compliance

This locknut features 5/16"-18 UNC coarse threading with Class 2B thread fit for precise dimensional accuracy and reliable mating compatibility. The manufacturing process adheres to strict quality standards, with compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The center lock distorted thread design provides consistent locking performance while maintaining the mechanical properties required for industrial fastening applications requiring vibration resistance and long-term reliability.
