Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address critical challenges in industrial settings, such as vibration-induced loosening and corrosion. The UNC coarse thread and Class 3A fit ensure precise engagement and high clamping force, ideal for securing components in machinery, automotive assemblies, and heavy equipment. Its headless design and flat tip allow for flush mounting, reducing protrusion risks and providing consistent pressure without marring surfaces. Made from robust alloy steel with a Rockwell C45 hardness, it withstands high stress and repetitive loads, while the hex drive enables efficient installation in confined spaces. This screw delivers reliable performance in applications requiring right-hand threading and coarse pitch for quick, durable fastening solutions.
Specification Summary & Compliance
This set screw features a 1/2"-13 UNC coarse thread with Class 3A thread fit for high precision and strength. It adheres to ASME B18.3 manufacturing specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability in industrial use.
