Professional Applications & Engineering Value
Engineered for heavy-duty industrial use, this black-oxide alloy steel set screw addresses common challenges like component slippage and corrosion in machinery assemblies. The UNC coarse thread and Class 3A fit ensure tight, reliable engagement in high-vibration environments, such as automotive drivetrains or construction equipment. Its hex socket drive and cup tip provide superior torque control and surface contact, reducing the risk of loosening over time. Ideal for securing gears, pulleys, and couplings, this fastener enhances assembly longevity and minimizes maintenance needs, backed by ASME B18.3 specifications for consistent quality.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including UNC thread with Class 3A fit for tight tolerances and optimal performance. Manufactured in compliance with ASME B18.3 and meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it ensures environmental safety and material reliability. The Rockwell C45 hardness and black-oxide surface treatment further support its use in rigorous industrial applications.
