S-95030A160 3/8"-24 Locknuts

Key Features & Benefits at a Glance

• Secure vibration-resistant locking through cotter pin insertion (7/64" diameter) prevents unintentional loosening in high-stress applications
• Superior corrosion protection with zinc-plated steel construction ensures long-term durability in harsh industrial environments
• Precision thread engagement with Class 2B fit provides consistent clamping force and reduces cross-threading risks
• Enhanced installation efficiency with standard external hex design allows for quick assembly using common wrench tools
• Reliable fine thread performance with 3/8"-24 UNF specification offers better tension control in critical mechanical assemblies
• Optimized slot dimensions (0.11" min. depth, 0.12" min. width) ensure smooth cotter pin installation and secure retention
• Compliance with international standards including REACH and RoHS 3 demonstrates environmental responsibility and global market suitability

Professional Applications & Engineering Value

This zinc-plated steel castle locknut delivers critical safety performance in mechanical systems where vibration-induced loosening poses significant operational risks. The 3/8"-24 UNF fine thread configuration maintains precise tension under dynamic loads, while the castle design with cotter pin slot provides mechanical locking that surpasses friction-based alternatives. Engineered for heavy-duty industrial applications including agricultural machinery, automotive suspensions, and construction equipment, this external hex locknut combines the installation convenience of standard wrenching with the fail-safe security of positive mechanical locking. The zinc plating extends service life in exposed environments, making it ideal for outdoor equipment and marine applications where corrosion resistance is paramount.

Specification Summary & Compliance

This locknut features Class 2B thread fit per UNF standards, ensuring proper engagement with mating components. Dimensions include 9/16" width across flats and 21/64" height for standardized tool compatibility. The product is manufactured in compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives, confirming adherence to hazardous substance restrictions. Cotter pin compatibility is specified for 7/64" diameter pins with minimum slot dimensions of 0.11" depth and 0.12" width to guarantee reliable installation and retention.
