Professional Applications & Engineering Value
Engineered for precision locking applications, this black-oxide alloy steel set screw delivers critical performance in industrial machinery, automotive assemblies, and power transmission systems. The headless design with hex drive enables flush mounting in confined spaces while providing substantial torque capability. The UNC coarse threads combined with Class 3A fit create reliable engagement in soft metals and plastics without stripping threads. The cup tip configuration concentrates clamping force for secure shaft collars and pulley retention, while the corrosion-resistant black-oxide finish protects against degradation in humid or chemically aggressive environments. This combination addresses common assembly challenges including vibration loosening, space constraints, and environmental durability requirements.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread tolerance for precision fit. The 3/8"-16 UNC coarse thread maintains standard compatibility while the 2" length provides versatile application coverage. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility. Material certification confirms Rockwell C45 hardness and black-oxide surface treatment meeting industrial corrosion protection standards.
