• Extended tip design (0.125" length) allows for deeper penetration and improved grip on components, minimizing loosening in dynamic settings.
• Compliance with ASTM F912 standards ensures consistent quality and performance, meeting rigorous industrial specifications.
• RoHS 3 and REACH compliance guarantees environmental safety and regulatory adherence for global supply chain integration.

Professional Applications & Engineering Value

This 1/2"-13 UNC square head set screw is engineered to address common challenges in industrial assembly, such as vibration-induced loosening and torque management. Constructed from black-oxide alloy steel, it offers robust resistance to corrosion and mechanical stress, making it ideal for machinery, automotive, and construction applications. The extended tip enhances clamping force by penetrating deeper into mating parts, while the coarse thread and Class 2A fit facilitate quick installation without compromising precision. By integrating high Rockwell C45 hardness and standardized dimensions, this screw delivers reliable performance in demanding environments, reducing maintenance needs and improving operational efficiency for B2B clients.

Specification Summary & Compliance

This set screw features precise dimensional tolerances, including a Class 2A thread fit for consistent engagement and an extended tip with tight length and diameter tolerances (e.g., tip length tolerance of -0.005" to 0.005"). It adheres to UNC coarse thread standards and is manufactured in compliance with ASTM F912 specifications. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory conformity for industrial use.
