• Reliable performance meeting ASME B18.3 specifications for dimensional consistency
• Environmental compliance with RoHS 3 and REACH regulations for safe industrial use

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical performance in demanding applications where vibration resistance and permanent positioning are essential. The UNC coarse threads with Class 3A precision fit provide superior engagement in soft materials and prevent loosening under dynamic loads. The 90° cone point creates concentrated pressure for maximum grip on shafts, collars, and pulleys in power transmission systems. Engineered for industrial machinery, automotive assemblies, and manufacturing equipment, this headless set screw offers reliable fastening where flush mounting is required while maintaining exceptional strength through Rockwell C45 hardness rating.

Specification Summary & Compliance

Manufactured to exacting ASME B18.3 standards with Class 3A thread fit for precision tolerance. Features 5/16"-18 UNC coarse threads with right-hand direction and 1-3/4" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment on alloy steel substrate provides corrosion protection while maintaining dimensional stability across industrial applications.
