Professional Applications & Engineering Value
This 12-point flange screw delivers critical engineering solutions for heavy-duty assembly challenges where maximum torque transmission and vibration resistance are paramount. The alloy steel construction with Rockwell C37 hardness ensures reliable performance in high-stress applications including heavy machinery, automotive systems, and industrial equipment. The UNF fine threading with Class 3A fit provides precise engagement that prevents loosening under dynamic loads, while the integrated flange design distributes clamping force effectively without requiring additional components. Engineered for external 12-point drive systems, this fastener enables efficient installation in confined spaces where conventional tools cannot access, making it ideal for maintenance-critical and high-vibration environments across multiple industrial sectors.
Specification Summary & Compliance
This precision fastener features 1/2"-20 UNF fine threading with Class 3A fit ensuring tight tolerances for critical assemblies. Manufactured to IFI 115 specifications with complete RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, meeting the latest environmental and safety standards. The inch system measurement provides dimensional consistency, while the fully threaded design and right-hand thread direction deliver reliable performance across industrial applications requiring high-strength fastening solutions.
