Professional Applications & Engineering Value
This M12 flange nut with A286 Stainless Steel construction addresses common industrial challenges like thermal expansion, corrosion, and vibration loosening. The integrated flange design distributes clamping force evenly, protecting soft materials and reducing stress concentrations in automotive and aerospace assemblies. Its 12-point external drive enables high-torque installation in confined spaces, while the coarse metric thread ensures rapid assembly in production lines. The Class 5H thread fit maintains precision under dynamic loads, making it ideal for engines, structural frames, and high-temperature equipment where reliability is non-negotiable.
Specification Summary & Compliance
Manufactured to metric standards with M12 x 1.75mm coarse threads and Class 5H thread fit for precise engagement. Dimensions include 20.9mm flange diameter, 3.2mm flange thickness, 14mm width, and 12.8mm height. Complies with international metric fastener specifications and RoHS/REACH environmental directives, ensuring suitability for global industrial and aerospace applications requiring consistent performance and material safety.
