Professional Applications & Engineering Value

This 5/16"-18 UNC fully threaded rod is engineered to address common industrial challenges such as structural loosening, corrosion-induced failure, and assembly inefficiency. Constructed from zinc-plated steel, it provides a robust barrier against moisture and chemicals, making it ideal for construction frameworks, machinery anchoring, and electrical conduit supports where environmental exposure is a concern. The coarse UNC thread and Class 1A fit facilitate rapid installation in field applications, reducing labor time while the 50,000 psi tensile strength ensures long-term structural integrity under static and dynamic loads. Its 4-foot length and full threading allow for precise custom cutting, offering flexibility in manufacturing, HVAC systems, and heavy-duty fastening projects without compromising on performance or compliance.

Specification Summary & Compliance

This threaded rod adheres to Unified Coarse (UNC) thread standards with a Class 1A thread fit for inch-system applications, ensuring dimensional accuracy and interchangeability. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, confirming the absence of restricted hazardous substances. Manufactured from zinc-plated steel, it maintains a tensile strength of 50,000 psi and a hardness of Rockwell B61, suitable for general-purpose and industrial use under specified load conditions.
