Hexagon Nut DIN 6330B M20, SW 30 mm – AMF, Strength Class 10

A Hexagon Nut DIN 6330B M20 intended for high-tensile bolted joints in industrial and workshop applications.

• Conforms to DIN 6330B standard
• Strength class 10 for high loads
• M20 thread size for standard fittings
• Wrench size SW 30 mm for fast assembly

Reliable connection for heavy-duty assemblies

The Strength class 10 rating provides a clear, measurable advantage when securing load-bearing joints: higher tensile and proof loads reduce the risk of fastener failure under stress. Matched with the M20 thread size and a defined overall height of 30 mm, this hexagonal fastener ensures consistent thread engagement across repeated assemblies. Engineers and maintenance teams gain predictable clamping behaviour, which simplifies torque specification and quality checks in production or repair processes.

Designed for efficient installation and maintenance

A compact SW 30 mm hex profile speeds up manual and machine-assisted tightening, while the standardised geometry allows the use of common spanners and sockets across maintenance fleets. The nut’s conformance to DIN 6330B means interchangeability with other components specified to the same norm, reducing procurement complexity. Fewer tool changes and uniform torque targets translate into measurable time savings on assembly lines and during scheduled maintenance, supporting leaner workflows and lower downtime.

Traceability and application fit for industry

Marking and SKU traceability support inventory control and batch documentation for regulated sectors. The item is identified under SKU 4000833400NW and specified by its corner measure 33.5 mm and declared Strength class 10, which assists purchasing and quality departments in verifying compatibility with bolts and clamping elements. As a hexagonal fastener it suits a wide range of metal-joining tasks where standardised metrics and reproducible mechanical performance are priorities, from workshop repairs to machine assembly.
