Professional Applications & Engineering Value
This A286 stainless steel flange nut delivers critical performance advantages where corrosion resistance and structural reliability are paramount. The integrated flange design (45/64" diameter) distributes clamping force over wider surface areas, preventing material deformation in soft substrates while eliminating separate washer components. The external 12-point drive accommodates high-torque applications common in aerospace and heavy industrial equipment, while the Class 3B thread fit ensures zero backlash in vibration-prone environments. Manufactured from A286 stainless steel, this UNC coarse thread flange nut maintains mechanical properties at elevated temperatures, solving thermal expansion challenges in engine components and exhaust systems.
Specification Summary & Compliance
This flange nut features 7/16"-14 UNC coarse threads with Class 3B fit precision tolerances, right-hand thread direction, and standardized inch dimensions. The manufacturing process adheres to ASME/ANSI specifications for unified thread forms, while A286 material composition complies with aerospace standards for high-strength applications. The product meets RoHS and REACH environmental compliance requirements for industrial and international markets.
