S-93083A113 3/8"-24 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through serrated locking teeth that bite into mating surfaces, preventing loosening under dynamic loads
• Enhanced corrosion protection with black-oxide steel finish, extending service life in demanding industrial environments
• Precise thread engagement with Class 2B fit ensuring consistent torque values and reliable fastening performance
• Integrated flange design eliminates need for separate washers, distributing load across wider surface area
• Standard hex profile provides compatibility with common wrenching tools for easy installation and maintenance
• Fine UNF thread configuration offers superior holding power and resistance to vibrational loosening
• Environmental compliance meets REACH and RoHS 3 standards for safe use across regulated industries

Professional Applications & Engineering Value

This black-oxide steel flange locknut addresses critical vibration-induced failure points in industrial machinery, automotive assemblies, and heavy equipment. The serrated locking mechanism creates permanent resistance to rotational forces, maintaining clamp load integrity where conventional nuts fail. Engineered with 3/8"-24 UNF fine threads, the design provides superior tensile strength and fatigue resistance compared to coarse-thread alternatives. The integrated 3/4" flange distributes bearing pressure across wider surfaces, preventing material deformation in soft substrates. This combination of vibration-resistant locking and load-distributing flange makes it ideal for high-stress applications requiring maintenance-free performance and reliable secure fastening solutions.

Specification Summary & Compliance
