Professional Applications & Engineering Value

This zinc-plated steel flange lock nut delivers exceptional performance in demanding industrial environments where vibration resistance and reliable fastening are critical. The serrated locking mechanism creates permanent resistance to rotational loosening, making it ideal for automotive assemblies, heavy machinery, and structural applications subject to constant motion or impact loads. The integrated 1 1/2" flange eliminates the need for separate washers while providing superior load distribution across joined surfaces, preventing damage to softer materials. Engineered with UNF fine threads and Class 2B thread fit, this external hex drive nut ensures precise installation torque values and maintains clamping force integrity in high-stress applications, from manufacturing equipment to construction projects requiring dependable, long-term fastening solutions.

Specification Summary & Compliance

This flange lock nut features 3/4"-16 UNF fine threads with Class 2B thread fit for precise engagement and right-hand thread direction. The external hex drive measures 1 1/8" across flats with a 43/64" height profile. Manufacturing complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental responsibility and global market acceptance for industrial hardware applications.
