AMF hexagon nut DIN 6331 M20 — strength class 10, SW 30 mm

The AMF hexagon nut DIN 6331 M20 provides a high-strength fastening solution for industrial and workshop assemblies, specified for M20 threads and designed for reliable clamping under load.

• Hexagon nut to DIN 6331 standard
• Thread size M20, strength class 10
• Wrench size 30 mm for robust tightening
• Pressed and milled manufacturing, corner 33.5 mm

Consistent high-strength performance for critical joints

The M20 fastener is manufactured to DIN 6331 and rated strength class 10, delivering a clearly defined mechanical profile for demanding assemblies. This high strength classification indicates a fastener intended for elevated clamping forces and reduced risk of shear or tensile failure in service, which supports safer machine builds and structural joints. Specifying a component with a standardised class and norm reduces uncertainty in procurement and streamlines engineering documentation, making it suitable for production environments where reproducible results matter.

Precise fit reduces assembly time and improves repeatability

With a wrench size of 30 mm and an overall height of 30 mm, the geometry is optimised for mechanical accessibility and consistent torque application. The pressed and milled finish ensures accurate seating and minimal lateral play, while the corner measure 33.5 mm provides a clear reference for tightening tools and fixtures. These measurable dimensions simplify calibration of assembly processes and minimise rework: a tight fit and predictable tool engagement mean faster, safer installations and fewer interruptions on the shop floor.

Industrial compatibility and predictable behaviour in assemblies

Designed as a standard-compliant hexagon nut, this fastener integrates easily into existing bill of materials and clamping concepts. The production method and the strength class 10 rating contribute to long-term joint stability in applications subject to vibration or cyclical loading. For engineers and buyers seeking parts that conform to established specifications, the AMF part offers traceability and a dependable mechanical profile, supporting quality assurance routines and reducing the need for frequent replacements.
