Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance in demanding mechanical systems where vibration resistance and corrosion protection are paramount. The Class 3A thread fit and UNC coarse threading provide superior holding power in pulleys, gears, and collars, preventing loosening under dynamic loads. Engineered with a cup tip, it concentrates clamping force without marring shafts, while the headless design and hex drive enable flush mounting in confined spaces. Ideal for heavy machinery, automotive, and industrial equipment, this set screw ensures long-term reliability by combining high hardness (Rockwell C45) with environmental compliance, reducing maintenance and replacement costs.
Specification Summary & Compliance
This set screw maintains Class 3A thread tolerances per UNC standards, with a 7/16"-14 thread size and coarse spacing. Manufactured in accordance with ASME B18.3 and ASTM F912 specifications, it is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to international safety and environmental regulations for industrial use.
