S-8421N89 5/16"-24 Threaded Rods

Key Features & Benefits at a Glance

• Dual-thread versatility with both right-hand and left-hand threading allows for flexible assembly and disassembly in complex mechanical systems
• Carbon steel construction delivers excellent tensile strength and impact resistance for demanding industrial environments
• Hexagonal rod profile provides superior tool grip and torque application during installation and adjustment
• Full-length threading (1-1/4" on both ends) enables deep engagement and secure fastening in various mounting scenarios
• Precision 5/16"-24 thread pitch ensures consistent mating with standard nuts and components for reliable connections
• Regulatory compliance with RoHS 3 and REACH standards guarantees environmental safety and global market acceptance
• 4-inch overall length offers optimal sizing for space-constrained applications while maintaining structural integrity

Professional Applications & Engineering Value

This carbon steel threaded rod solves critical challenges in machinery assembly, maintenance fixtures, and adjustable framework systems. The unique dual thread direction configuration enables counter-rotational locking mechanisms and bidirectional adjustment capabilities that prevent accidental loosening under vibration. The hex-shaped rod allows direct wrench access without additional adapters, significantly reducing installation time in confined spaces. With both ends threaded to 1-1/4" depth, this component provides maximum thread engagement for load distribution across connected parts. Ideal for industrial clamping applications, automotive jigs, and production line equipment where right-hand and left-hand threading creates fail-safe connections in dynamic operating conditions.

Specification Summary & Compliance

Manufactured to standard 5/16"-24 thread specifications with Class 2A tolerance for consistent fit. The carbon steel material meets industrial strength requirements while the hex size of 5/16" ensures compatibility with standard tools. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as steel alloying element and REACH (EC 1907/2006) regulations (including 233 SVHC as of 01/17/2023) for chemical safety in industrial applications.
