Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications requiring permanent, vibration-resistant positioning. The Class 3A thread fit maintains precise tolerances in machinery components, pulleys, and collars where loosening could cause operational failure. With UNC coarse threading and Rockwell C45 hardness, it withstands extreme mechanical stress while the headless hex drive design enables flush mounting in space-constrained assemblies. The black-oxide surface treatment provides essential corrosion protection for manufacturing equipment, automotive systems, and heavy machinery exposed to harsh operating conditions, ensuring long-term reliability without maintenance interventions.
Specification Summary & Compliance
Manufactured to exact ASME B18.3 specifications with Class 3A thread fit precision and UNC 5/16"-18 coarse threading. The 1 3/4" length and 0.313" thread diameter maintain dimensional accuracy across production batches. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, alongside material certification to ASTM F912 standards for consistent performance in industrial applications.
