Key Features & Benefits at a Glance

  • Superior torque transmission with the external 12-point drive, preventing tool slippage in high-stress assembly applications
  • Exceptional load-bearing capacity due to the Alloy Steel construction with a 170,000 psi tensile strength, ensuring reliability in demanding environments
  • Precise and secure thread engagement with the Class 3A UNC coarse thread fit, minimizing the risk of cross-threading and vibration-induced loosening
  • Enhanced stability and distributed load from the integrated flange, which acts as a built-in washer to protect surfaces and improve joint integrity
  • Long-term durability and wear resistance provided by the Rockwell C37 hardness, maintaining performance over repeated use
  • Streamlined installation with the fully threaded design and right-hand coarse thread, allowing for faster driving and reduced assembly time
  • Compliance with rigorous industry standards including IFI 115, RoHS 3, and REACH, ensuring material safety and environmental responsibility

Professional Applications & Engineering Value

This 7/16"-14 UNC 12-Point Screw is engineered to address critical challenges in heavy machinery, structural assemblies, and high-vibration environments. The Alloy Steel material, combined with a Rockwell C37 hardness and 170,000 psi tensile strength, provides the structural integrity needed to withstand extreme mechanical stresses without failure. The external 12-point drive offers superior torque application, reducing the risk of fastener head damage during high-torque installation. Its flanged design eliminates the need for a separate washer, distributing clamp load effectively to prevent surface damage and maintain joint stability. The Class 3A thread fit ensures precise alignment and resistance to loosening under dynamic loads, making it ideal for applications in construction, automotive, and industrial equipment where reliability is paramount.

Specification Summary & Compliance

This screw adheres to a Class 3A thread fit for high precision in Unified National Coarse (UNC) threading. Manufacturing and material specifications conform to IFI 115. The product is fully 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.
