Professional Applications & Engineering Value

This 12-point flanged screw addresses critical engineering challenges in heavy machinery, automotive assemblies, and structural applications where high tensile strength and vibration resistance are paramount. The alloy steel construction with Rockwell C37 hardness provides exceptional durability against wear and fatigue, while the 7/16"-14 UNC coarse thread with Class 3A fit ensures precise engagement and maintains clamping force under dynamic loads. The integrated flange design eliminates the need for separate washers, distributing load evenly and preventing surface damage. The external 12-point drive allows for high-torque installation in confined spaces, making it ideal for industrial applications requiring reliable fastening solutions that meet stringent IFI 115 standards and environmental regulations.

Specification Summary & Compliance

This 12-point screw features precise Class 3A thread fit with 7/16"-14 UNC coarse threading and partial threading up to 1-3/8" minimum thread length. Manufacturing complies with IFI 115 specifications for dimensional accuracy and performance. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, ensuring environmental safety and regulatory adherence for industrial use across global markets.
