Professional Applications & Engineering Value

This 4-40 UNC threaded rod in brass delivers critical performance in applications where corrosion resistance and electrical conductivity are paramount. The fully threaded design with UNC coarse threads provides maximum thread engagement across the entire length, preventing loosening in vibrating environments common in industrial machinery, electrical enclosures, and marine equipment. The Class 2A thread fit ensures interchangeability with standard nuts while maintaining precise tolerances for reliable fastening. Engineers specify this rod for its combination of 50,000 psi tensile strength and non-sparking properties, making it ideal for hazardous locations and precision instrument assemblies where failure is not an option.

Specification Summary & Compliance

This threaded rod meets UNC coarse thread standards with Class 2A external thread fit for consistent dimensional accuracy. Manufacturing adheres to standard inch system specifications for 4-40 thread size and 1/2" length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it contains no restricted substances above threshold limits for industrial use worldwide.
