Key Features & Benefits at a Glance
- Enhanced corrosion resistance from the black-oxide finish, extending service life in demanding industrial environments.
- Superior strength and durability provided by alloy steel with a Rockwell C45 hardness, resisting wear and deformation under high stress.
- Secure and reliable fastening with the extended tip design, ensuring positive engagement and preventing component loosening.
- Efficient installation and removal using the external square drive and square head, allowing for high-torque application with standard tools.
- Precise thread fit with Class 2A UNC coarse threads, enabling quick assembly and consistent performance in right-hand applications.
- Broad industrial compatibility due to the 1/2"-13 thread size and 4" length, suitable for heavy-duty machinery and equipment.
- Compliance with global standards including ASTM F912, RoHS 3, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address critical challenges in industrial assembly, such as vibration-induced loosening and corrosion in harsh conditions. The extended tip provides deeper penetration and improved grip on shafts or collars, reducing the risk of slippage in high-torque applications like heavy machinery, automotive systems, and construction equipment. Made from robust alloy steel with a Rockwell C45 hardness, it offers exceptional shear and tensile strength, ensuring long-term reliability. The UNC coarse thread and Class 2A fit facilitate quick, secure installations, while the external square drive allows for efficient tightening with common wrenches, minimizing downtime in production environments.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent assembly and UNC coarse threads with a 1/2"-13 size. It meets ASTM F912 specifications for performance 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 global industrial use.
