S-96282A102 5/16"-18 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through precision-engineered serrations that bite into mating surfaces, preventing loosening under dynamic loads
• Exceptional strength and durability with Grade 8 classification, capable of withstanding extreme tension and shear forces in demanding applications
• Enhanced corrosion protection with zinc-plated steel construction, extending service life in harsh industrial environments
• Integrated flange design eliminates need for separate washers, providing larger bearing surface for improved load distribution
• Reliable coarse thread engagement with UNC 5/16"-18 threads and Class 2B fit for quick assembly and secure fastening
• Standard external hex drive enables easy installation with common wrenches, reducing assembly time and tooling requirements
• Full regulatory compliance with REACH and RoHS 3 standards, ensuring environmental responsibility and global market acceptance

Professional Applications & Engineering Value

This Grade 8 zinc-plated steel flange lock nut delivers critical performance in applications where vibration-induced loosening compromises safety and reliability. The precision serrations on the flange base create permanent locking action by embedding into contact surfaces, making it ideal for heavy machinery, automotive assemblies, construction equipment, and industrial manufacturing where constant motion and shock loads are present. The UNC coarse thread design ensures rapid installation while maintaining Class 2B thread fit accuracy for consistent torque values. The integrated 11/16" flange distributes clamping force over a wider area, reducing surface damage and preventing pull-through in softer materials. This combination of vibration resistance, exceptional strength, and corrosion protection addresses the primary failure modes in industrial fastening systems.

Specification Summary & Compliance

This flange lock nut features 5/16"-18 UNC coarse threads with Class 2B thread fit for precise engagement and reliable performance. The external hex drive (1/2" width) and standard hex profile ensure compatibility with industry-standard tools. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, confirming absence of restricted substances. The Grade 8 strength classification guarantees consistent mechanical properties, while the zinc-plated steel construction provides corrosion resistance suitable for various industrial environments.
