Professional Applications & Engineering Value

Engineered for demanding industrial fastening scenarios, this M7 flange nut addresses common assembly challenges through its specialized design. The black-oxide steel construction provides essential corrosion protection in automotive and machinery applications where exposure to moisture and chemicals is prevalent. The 12-point external drive configuration allows for higher torque application in confined spaces, preventing rounding and ensuring secure installations. Combined with the fine thread pitch and Class 5H thread fit, this metric fastener maintains clamping force under vibration, making it particularly valuable for engine components, hydraulic systems, and precision equipment where loosening could cause operational failures.

Specification Summary & Compliance

Manufactured to metric standards with M7x1mm fine threads and Class 5H thread tolerance for precision fit. Features standard 12mm flange diameter and 1.6mm thickness per industrial specifications. The black-oxide surface treatment complies with RoHS and REACH environmental standards, while the external 12-point drive conforms to common torque tool interfaces. Suitable for use in assemblies requiring consistent performance under ASME and ISO fastener guidelines.
