Professional Applications & Engineering Value
This Grade 8 flange nut delivers exceptional engineering value through its black-phosphate steel construction and integrated 3/4" flange diameter. The combination provides superior corrosion protection while distributing clamping force over a wider surface area, preventing surface damage and maintaining joint integrity in heavy-duty applications. The 3/8"-16 UNC coarse threads with Class 2B fit ensure rapid assembly in manufacturing lines and reliable performance in high-vibration environments like machinery, automotive systems, and structural frameworks. The external hex drive design accommodates standard wrenches for efficient maintenance operations, making it ideal for industrial equipment, construction projects, and transportation applications where durability and compliance with international standards are critical.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread fit and UNC coarse thread specifications. The nut features a 3/4" flange diameter with 0.07" thickness and 9/16" width across flats. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. Meets Grade 8 strength classification requirements for high-stress applications.
