Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address critical challenges in industrial fastening, such as loosening under vibration and corrosion in demanding settings. The Class 3A thread fit and UNF fine threads provide tight tolerances and enhanced grip, reducing the risk of assembly failure in machinery, automotive, and aerospace components. The cup point tip ensures positive engagement with shafts or hubs, preventing rotational movement in high-torque applications. Combined with its hex drive for easy access and the durable black-oxide finish for resistance to moisture and chemicals, this set screw delivers long-term reliability, minimizing maintenance needs and downtime in heavy-duty fastening scenarios.
Specification Summary & Compliance
This set screw adheres to precise Class 3A thread fit and UNF 3/4"-16 fine thread standards, ensuring dimensional accuracy and interchangeability. It meets ASME B18.3 manufacturing specifications for consistency and performance. Additionally, the product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in environments with strict environmental and health standards.
