S-95475A539 1/4"-20 x 5/8" Threaded Rods

Key Features & Benefits at a Glance

• Exceptional tensile strength of 50,000 psi ensures reliable load-bearing capacity in demanding industrial applications
• Superior corrosion resistance through zinc plating extends service life in harsh environments and outdoor conditions
• Precision Class 1A thread fit guarantees smooth assembly and consistent performance with mating components
• Full threading along entire 5/8" length provides maximum flexibility for positioning nuts and fasteners at any point
• Rockwell B61 hardness rating maintains thread integrity and prevents deformation under repeated use
• UNC coarse thread pattern enables quick installation and reduced cross-threading risks in time-sensitive operations
• Comprehensive regulatory compliance with RoHS 3 and REACH standards ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

This 1/4-20 UNC threaded rod delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc-plated steel construction combats corrosion in manufacturing facilities, construction sites, and mechanical assemblies exposed to moisture. With its fully threaded design and right-hand coarse threading, it enables rapid adjustments in conveyor systems, machinery frames, and electrical enclosures. The 50,000 psi tensile strength provides a safety margin for overhead applications and load-bearing structures, while the Class 1A thread fit ensures compatibility with standard nuts and fixtures. This rod eliminates galling and seizing issues common in inferior fasteners, reducing maintenance downtime in continuous operation environments.

Specification Summary & Compliance

Manufactured to precise UNC coarse thread standards with Class 1A external thread fit tolerance for consistent mating performance. The 1/4"-20 thread size and 5/8" length maintain dimensional accuracy across production batches. Compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations regarding chemical safety. The zinc-plated steel material and Rockwell B61 hardness provide documented mechanical properties suitable for industrial quality control requirements.
