S-94828A420 5/16"-18 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through Flex-Top locking technology that maintains consistent clamping force under dynamic loads
• Enhanced durability and corrosion protection with cadmium-plated steel construction for extended service life in harsh environments
• Optimal space utilization with extra-wide thin profile design that provides maximum bearing surface in confined applications
• Reliable thread engagement with Class 2B thread fit ensuring smooth installation and consistent performance
• Easy installation and removal using standard wrench tools thanks to the external hex drive design
• Secure fastening in high-vibration applications with right-hand UNC coarse threads that resist loosening under stress
• Versatile industrial compatibility with standard 5/16"-18 thread size fitting common equipment and machinery

Professional Applications & Engineering Value

This extra-wide thin hex locknut delivers exceptional engineering value in demanding industrial environments where vibration-induced loosening compromises safety and performance. The cadmium-plated steel construction provides superior corrosion resistance for extended service life in manufacturing, automotive, and heavy equipment applications. The Flex-Top locking mechanism creates consistent elastic deformation that maintains clamping force without damaging mating threads, making it ideal for assembly lines, machinery mounts, and structural frameworks. With its UNC coarse threads and Class 2B thread fit, this locknut ensures reliable installation while the extra-wide thin profile distributes load effectively across surfaces, preventing damage to softer materials and providing secure fastening in space-constrained applications where standard nuts cannot perform effectively.

Specification Summary & Compliance

This 5/16"-18 UNC locknut features Class 2B thread fit for precise dimensional accuracy and smooth assembly. The fastener complies with industry standards for external hex drive configurations and right-hand coarse threading. Manufacturing follows established industrial specifications for cadmium-plated steel fasteners, providing reliable performance in various industrial applications. The product meets standard industrial requirements for dimensional consistency and mechanical properties suitable for commercial and industrial use.
