Professional Applications & Engineering Value
Engineered for demanding industrial settings, this black-oxide alloy steel set screw combines material strength and precise UNC coarse threading to address common challenges like component loosening and corrosion. The headless design with a 3/4" hex drive enables secure, space-saving installations in machinery, automotive systems, and power transmission equipment, where vibration resistance is critical. Its Class 3A thread fit ensures minimal tolerance deviations, reducing the risk of assembly failures. The cup tip enhances grip on rotating parts, making it ideal for securing collars, gears, and pulleys without damaging surfaces, while the black-oxide finish provides an added layer of protection against rust in humid or abrasive conditions.
Specification Summary & Compliance
This set screw adheres to inch system measurements with a 1 1/2"-6 UNC coarse thread and Class 3A thread fit for high precision. It meets ASME B18.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for international industrial applications.
