Professional Applications & Engineering Value

This aluminum threaded rod solves critical engineering challenges where weight reduction, corrosion resistance, and regulatory compliance intersect. The round rod shape with 3/4" OD provides optimal strength-to-weight ratio, making it ideal for aerospace components, electronic enclosures, and machinery where every ounce matters. The 5/8"-18 thread specification with right-hand direction ensures compatibility with standard industrial components while the both ends threaded configuration eliminates the need for additional adapters in structural assemblies. Manufacturers benefit from the aluminum material's natural oxidation resistance, which prevents rust formation in humid environments without requiring surface treatments. This rod particularly excels in applications requiring REACH and RoHS compliance while maintaining the durability needed for repeated disassembly and reassembly cycles in maintenance operations.

Specification Summary & Compliance

This threaded rod features precision 5/8"-18 unified thread with standard Class 2A tolerances for reliable fit with matching female threads. The 3/4" outer diameter maintains consistent dimensions along the entire 18-inch length, while the 1 5/8" thread length on both ends provides sufficient engagement for secure fastening. Manufacturing complies with industry standards for round threaded rods, and the product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(b)-II for lead as an alloying element in aluminum, along with meeting the latest REACH (EC 1907/2006) requirements as of January 2023, including 233 Substance of Very High Concern (SVHC) compliance.
