Robust fastening with standard conformity and high tensile capacity; the combination of DIN 6331 compliance and strength class 10 provides reliable performance in demanding assemblies. The precision milled faces and a defined SW 19 width ensure consistent torque behaviour. Order the hexagon nut directly via Metav Werkzeuge or ask our consultants if needed.

Hexagon nut DIN 6331 M12 SW 19 mm, strength class 10 — AMF

A hexagon nut DIN 6331 M12 for high-strength machine and assembly applications, precision pressed and milled to ensure a secure, repeatable clamping connection.

• DIN 6331 compliant fastening element
• M12 thread and strength class 10
• Width across flats 19 mm (SW 19)
• Overall height 18 mm, corner size 21.1 mm

Consistent load-bearing performance for critical joints

The nut is manufactured to meet DIN 6331, which assures dimensional compatibility with industry-standard threaded connections. With strength class 10, the part offers a higher load capacity than lower classes, making it suitable for assemblies exposed to elevated tensile stresses. The standardised geometry simplifies component selection in production planning and maintenance schedules, reducing the risk of mismatched parts and unplanned downtime. This technical conformity supports predictable mechanical behaviour under load.

Predictable torque and seating through precision geometry

Precision in contact surfaces matters for reliable clamping. The nut’s precision-milled faces minimise seating irregularities and ensure the applied torque translates into consistent preload. The SW 19 spanner size and overall height 18 mm define the working envelope for tools and tightening procedures, while the corner size 21.1 mm supports secure engagement with sockets and wrenches. Clear specification of these dimensions reduces assembly variance and helps maintain joint integrity over repeated service intervals.

Easy specification, ordering and integration into existing systems

As a standard M12 component, the part integrates directly with common fasteners and fixtures, simplifying procurement and stock management. The clearly documented dimensions and the DIN reference enable quick cross-referencing in technical drawings and procurement lists. Single-unit packaging supports spare-part provisioning for repair shops and small-batch production runs. Where clarity is required during selection, the concise dimension set and compliance data enable rapid decision-making within engineering and purchasing workflows.

FAQ

What standard does this nut comply with?
The nut is manufactured to DIN 6331, ensuring standardised dimensions and interchangeability with M12 threaded components.

Is this hexagon nut suitable for high-load applications?
Yes—its strength class 10 rating identifies it as appropriate for higher tensile demands compared with lower strength classes.

Which spanner size is required for tightening?
The specified width across flats is 19 mm (SW 19), so a 19 mm spanner or socket should be used for assembly and maintenance.

What dimensions should be checked before selecting this nut for an assembly?
Confirm the M12 thread compatibility, the overall height 18 mm, and the SW 19 width across flats to ensure tool fit and correct seating in the intended application.
