Key Features & Benefits at a Glance
- Maximum torque transfer with the external 12-point drive and 1/2" drive size, enabling secure installation in high-stress assemblies.
- Superior tensile strength and durability from alloy steel construction, rated at 170,000 psi to prevent failure under extreme loads.
- Enhanced hardness and wear resistance with a Rockwell C37 rating, ensuring long-term performance in demanding environments.
- Precise and reliable thread engagement due to the Class 3A thread fit and UNC coarse spacing, reducing the risk of cross-threading and ensuring consistent clamping force.
- Integrated flange design with a 0.75" diameter, providing a larger bearing surface to distribute load and eliminate the need for a separate washer.
- Full threading along the 1" length allows for maximum adjustability and grip in deep or variable material thicknesses.
- Compliance with major industrial standards including IFI 115, RoHS 3, and REACH, ensuring safety, environmental responsibility, and global acceptance.
Professional Applications & Engineering Value
This 12-point flanged screw is engineered for high-torque applications where reliability is non-negotiable. The alloy steel composition, combined with a Rockwell C37 hardness and 170,000 psi tensile strength, provides exceptional resistance to shear and vibration, making it ideal for heavy machinery, automotive assemblies, and structural frameworks. The external 12-point drive allows for efficient wrenching in confined spaces, while the UNC coarse thread and Class 3A fit ensure quick assembly and reduced galling. The integrated flange enhances joint stability by distributing stress over a wider area, preventing loosening and surface damage. This screw delivers consistent performance in industrial fastening scenarios requiring both high strength and precision.
Specification Summary & Compliance
This screw features a 1/2"-13 UNC thread with coarse spacing and a Class 3A precision fit for optimal thread engagement. It is manufactured in accordance with IFI 115 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
