S-8420K178 5/8"-18 Threaded Rods

Key Features & Benefits at a Glance

• Lightweight & Corrosion-Resistant: Crafted from durable aluminum, this rod offers excellent strength-to-weight ratio and natural resistance to rust, ideal for applications where weight and environmental factors are a concern.
• Secure Dual-End Threading: Features 5/8"-18 threading on both ends, providing versatile and reliable connection points for a wide range of assembly requirements.
• Unique Dual Thread Direction: Incorporates both right-hand and left-hand threads, enabling specialized applications for adjustment, locking, or tensioning mechanisms that require counter-rotational forces.
• Easy Installation & Adjustment: The integrated 5/8" hex shape along the rod allows for easy gripping with standard wrenches, facilitating quick installation, removal, and precise adjustments.
• Precision Thread Engagement: With a generous 1 3/4" thread length on each end, it ensures deep and secure engagement with mating components, enhancing joint integrity and load distribution.
• Comprehensive Compliance: Manufactured to be RoHS 3 and REACH compliant, ensuring it meets stringent international standards for hazardous substances, making it suitable for regulated industries and global supply chains.
• Robust 4-Inch Design: The 4-inch overall length provides a compact yet sturdy solution for spacing, coupling, or extending components in tight assemblies.

Professional Applications & Engineering Value

This aluminum hex threaded rod is engineered to solve critical challenges in machinery, automation, and structural frameworks. Its dual thread direction (right-hand and left-hand) is specifically valuable in applications requiring opposing motion, such as in jacks, clamps, or leveling systems, where one end tightens while the other loosens. The hex shape eliminates the need for additional locking tools during installation, speeding up assembly times in production lines. Made from aluminum, it significantly reduces overall system weight without compromising on strength, making it ideal for aerospace, automotive, and portable equipment. The combination of both ends threaded and precise 5/8"-18 thread size ensures reliable performance in high-vibration environments, preventing unintended loosening and maintaining long-term operational safety.

Specification Summary & Compliance

This threaded rod adheres to standard inch system measurements with a 5/8"-18 thread size and is manufactured from aluminum with a hex rod shape for easy handling. It is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(b)-II for lead as an alloying element in aluminum, and REACH (EC 1907/2006) regulations, ensuring it meets the latest environmental and safety standards for industrial components.
