• Efficient installation with standard external hex drive design allowing for high torque application using common tools
• Reliable thread engagement with Class 2B thread fit ensuring consistent performance and easy assembly
• Integrated flange design eliminates need for separate washers, distributing clamp load over wider surface area
• Heavy-duty construction from steel material providing high strength-to-weight ratio for demanding applications
• Regulatory compliance meeting both RoHS 3 and REACH standards for environmental and safety requirements

Professional Applications & Engineering Value

This zinc-flake-coated steel flange locknut delivers exceptional performance in high-vibration environments where traditional fasteners fail. The serrated locking mechanism creates permanent resistance to rotational loosening, making it ideal for heavy machinery, automotive assemblies, and structural applications. The integrated 1-1/32" flange provides superior bearing surface distribution, reducing point loading and material stress. With UNC coarse threading and Class 2B thread fit, this fastener ensures rapid assembly while maintaining precise tolerances. The external hex drive accommodates standard wrenches for efficient installation in confined spaces. Engineered for industrial reliability, this flange locknut solves critical challenges in equipment that experiences constant vibration, thermal cycling, and dynamic loading conditions.

Specification Summary & Compliance

This flange locknut features 1/2"-13 UNC coarse threads with Class 2B thread fit for consistent engagement and reliable performance. The external hex drive measures 3/4" across flats with an overall height of 29/64". The flange diameter measures 1-1/32" with a thickness of 0.05". Manufactured from steel with zinc-flake coating for corrosion protection and featuring right-hand thread direction with serrated locking mechanism. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in industrial applications worldwide.
