Professional Applications & Engineering Value

This heavy-duty flange nut is engineered to address critical challenges in industrial assembly where vibration resistance and consistent clamping force are paramount. The black-oxide steel construction provides essential corrosion protection in harsh operating conditions, while the integrated 1 5/8" flange distributes load evenly across surfaces, preventing damage to softer materials. The 3/4"-16 UNF fine thread configuration offers superior holding power in high-stress applications, making it ideal for automotive, machinery, and structural assemblies where precision thread engagement and reliable fastening performance are non-negotiable. The external hex drive ensures compatibility with standard industrial tools, streamlining installation and maintenance procedures.

Specification Summary & Compliance

This flange nut features Class 2B thread fit per UNF standards, ensuring precise dimensional accuracy and reliable mating performance. Manufactured from black-oxide steel with a 1 5/8" flange diameter and 0.25" flange thickness, the component maintains RoHS 3 (2015/863/EU) compliance with exemption 6(a) for lead as an alloying element in steel. The 3/4"-16 UNF fine thread configuration adheres to inch system measurement standards, providing consistent performance in industrial fastening applications requiring right-hand thread direction and standard hex nut profile compatibility.
