Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with 170,000 psi tensile strength for reliable performance in high-stress applications.
- Superior wear resistance and durability due to alloy steel construction and Rockwell C37 hardness.
- Precise and secure fastening ensured by the Class 3A thread fit, minimizing the risk of loosening under vibration.
- Efficient installation and removal with the external 12-point drive, providing high torque capability and tool accessibility.
- Enhanced stability and distribution of load from the integrated flange, reducing the need for separate washers.
- Optimized for coarse-thread applications using 1/4"-20 UNC threading, ideal for quicker assembly in less brittle materials.
- Safe for regulated environments with compliance to IFI 115, RoHS 3, and REACH, ensuring environmental and safety standards are met.
Professional Applications & Engineering Value
This 12-point flange screw is engineered to address critical challenges in heavy-duty industrial assemblies, such as machinery, automotive, and construction equipment. Its alloy steel composition and Rockwell C37 hardness provide excellent resistance to shear and fatigue, preventing failure in high-vibration settings. The UNC coarse thread and Class 3A thread fit ensure tight, reliable connections, reducing maintenance needs and downtime. The external 12-point drive allows for high-torque application with standard tools, speeding up installation in confined spaces. Ideal for applications requiring flanged screws with partial threading, it offers a robust solution for securing components without compromising on precision or regulatory compliance.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including Class 3A thread fit for tight tolerances and UNC coarse threading with a 1/4"-20 size. It meets IFI 115 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 safe for various industrial uses.
