9mm Hexagon Nut DIN 6331 M6 Thread Strength 10, Corner Size 11.05 - AMF

Reliable fastening performance follows from DIN 6331 conformity and strength class 10, combined with precise corner machining for consistent torque transmission. The compact 9 mm overall height and SW 10 mm design allow space-saving assemblies. Order the hexagon nut directly via Metav Werkzeuge or ask our consultants for application-specific advice.

Hexagon nut DIN 6331 M6 — pressed and milled, Strength class 10 (AMF)

the Hexagon nut DIN 6331 M6 is a standard-compliant industrial fastener for high-strength mechanical and assembly applications

• DIN 6331 standard compliance
• Strength class 10 for high load
• Wrench size SW 10 mm
• Precision milled corners 11.05 mm

Consistent clamping force for repeatable assemblies

The DIN 6331 specification defines tight dimensional tolerances that enable reproducible fit and torque behaviour in series production. With a thread size M6 and strength class 10, the fastener provides elevated mechanical resistance compared with lower classes, which translates into increased load capacity in bolted joints. Engineers and purchasers benefit from fewer rework cycles because the fastener geometry and hardness are designed to maintain clamping force under cyclic loading.

Durable manufacturing that reduces installation issues

Manufactured by a combination of forming and machining, the pressed and milled production method ensures economical blanks with precision-corner machining where needed. The SW 10 mm flats and corner size 11.05 mm are milled to reduce rounding under spanners, improving serviceability in assembly lines and maintenance operations. The compact 9 mm overall height minimises axial space while retaining sufficient thread engagement for secure joints in confined assemblies.

Simple integration into standard workflows

As a metric hexagon nut, the component fits existing M6 bolt inventories and common tool sets without special adapters. Traceability is supported through the SKU and product labelling, enabling streamlined stock management and quality checks. The design reduces handling complexity on the workshop floor and supports predictable assembly times, which is particularly valuable in repetitive or automated fastening processes.

FAQ

What thread and bolt sizes are compatible with this nut?
The Hexagon nut DIN 6331 M6 (AMF, SKU 4000833405NW) matches standard M6 metric threads and is compatible with M6 bolts and studs manufactured to corresponding metric specifications.

What does strength class 10 indicate for this nut?
Strength class 10 denotes a high mechanical resistance level for the AMF hexagon nut, indicating elevated tensile and yield performance relative to lower classes and suitability for higher-load bolted joints.

Is the nut suitable for tight or confined assembly spaces?
Yes — the compact 9 mm overall height and SW 10 mm flats make the hexagon nut DIN 6331 M6 suitable for space-restricted assemblies where reliable thread engagement is required.

How precise are the external dimensions of the nut?
Dimensions comply with DIN 6331 and include a milled corner measure of 11.05 mm, which is intended to ensure consistent spanner fit and minimise rounding during installation.
