S-8421N83 5/16"-24 Threaded Rods

Key Features & Benefits at a Glance

• Enhanced installation versatility with both right-hand and left-hand threading on a single rod, allowing for bidirectional adjustment and locking in specialized assemblies.
• Superior torque application and grip provided by the hex-shaped rod, enabling easy wrenching and reducing slippage during installation.
• Robust and durable performance from high-strength carbon steel construction, ensuring reliable load-bearing capacity and resistance to wear in demanding environments.
• Precise and secure fastening with 5/16"-24 unified thread size, maintaining consistent engagement and reducing the risk of cross-threading.
• Ample threading engagement with 3/4" thread length on both ends, providing sufficient contact area for strong, stable connections.
• Compliance with stringent environmental regulations, meeting RoHS 3 and REACH standards for safe use in regulated industrial markets.
• Compact and adaptable design with a 3" overall length, ideal for space-constrained applications requiring dual-threaded connectivity.

Professional Applications & Engineering Value

This carbon steel threaded rod is engineered to address common challenges in machinery, automotive, and fixture assembly where dual thread direction is critical. The inclusion of both right-hand and left-hand threading on a single hex rod allows for opposing motion applications—such as tensioning systems or adjustable linkages—that require one end to tighten while the other loosens. The 5/16"-24 thread size and 3/4" thread length ensure deep, secure engagement, minimizing vibration-induced loosening. Made from durable carbon steel, it withstands high-stress conditions, while the hex shape offers superior grip for torque-intensive installations. Ideal for industrial fastening solutions in manufacturing and maintenance, this rod provides reliable performance where precision and adjustability are paramount.

Specification Summary & Compliance

This threaded rod adheres to unified 5/16"-24 thread specifications with standard Class 2A tolerance for consistent fit. The hex size is 5/16", and overall length is 3" with both ends threaded to 3/4". It is manufactured from carbon steel for strength and durability. The product is RoHS 3 (2015/863/EU) compliant under exemption 6(a) for lead in steel, and REACH (EC 1907/2006) compliant as of January 17, 2023, supporting its use in regulated industrial applications.
