Professional Applications & Engineering Value

This 5/16"-18 UNC left hand threaded rod is engineered to address critical challenges in industrial settings where standard right-hand threads may loosen under counter-clockwise motion. The zinc-plated steel material provides a durable barrier against rust and corrosion, making it ideal for outdoor equipment, automotive assemblies, and machinery subjected to moisture or chemicals. Its coarse UNC thread design ensures quick engagement and high resistance to vibration, while the fully threaded 6-foot length offers flexibility for custom fabrication in construction, maintenance, and manufacturing. With a tensile strength of 50,000 psi, it supports heavy-duty applications such as conveyor systems, scaffolding, and agricultural implements, delivering reliable performance where safety and precision are paramount.

Specification Summary & Compliance

This threaded rod adheres to UNC coarse thread standards with a Class 1A thread fit for external threads, ensuring dimensional accuracy and interchangeability. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of hazardous substances and suitable for industrial use globally. Manufactured from high-strength steel with a zinc plating finish, it maintains consistent performance in accordance with industry specifications for threaded fasteners.
