Professional Applications & Engineering Value

This M10 flange nut engineered with A286 stainless steel delivers exceptional performance in demanding industrial environments where corrosion resistance and mechanical strength are critical. The integrated 17.8mm flange provides superior load distribution, eliminating the need for separate washers while preventing surface damage and maintaining joint integrity under vibration. The external 12-point drive accommodates high-torque installation tools, ensuring secure fastening in confined spaces common to machinery, automotive, and aerospace applications. With its coarse thread pitch and Class 5H thread fit, this metric flange nut resists loosening under dynamic loads while enabling rapid assembly in production environments.

Specification Summary & Compliance

This M10 x 1.5mm metric flange nut features Class 5H thread tolerance per ISO standards, ensuring precise fit with mating components. The nut maintains dimensional accuracy with 12mm width across flats and 10.2mm height, complemented by a 3.2mm flange thickness for optimal strength. Manufactured from A286 stainless steel, this right-hand thread fastener meets industry standards for mechanical properties and is compliant with RoHS and REACH environmental directives for industrial use.
