Professional Applications & Engineering Value
This M11 flange nut is engineered to address common challenges in industrial fasteners, such as vibration-induced loosening and corrosion in demanding settings. The black-oxide steel material provides a protective layer that resists rust and wear, extending service life in automotive and heavy machinery applications. Its metric fine thread with a 1.25mm pitch ensures tight, secure fits, minimizing the risk of failure under dynamic loads. The integrated flange design distributes clamping force evenly, eliminating the need for separate washers and speeding up assembly processes. Combined with the external 12-point drive, it allows for efficient installation in confined spaces, making it a reliable choice for engineers seeking durability and precision in class 5H thread systems.
Specification Summary & Compliance
This flange nut adheres to metric standards with precise dimensions: M11 thread size, 1.25mm fine pitch, and Class 5H thread fit for consistent accuracy. It features a flange diameter of 17.8mm and thickness of 3.2mm, ensuring compliance with common industrial specifications. The product is manufactured to meet general industry norms and is suitable for applications requiring RoHS and REACH compliance, supporting safe and sustainable use in various sectors.
