21mm Hexagon Nut M14 DIN 6330B Strength Class 10, Height 21mm - AMF

Reliable fastening for mechanical assemblies is achieved by the M14 thread and strength class 10 combined with a 21 mm spanner width, ensuring consistent clamping force and repeatable installation; order this component directly via Metav Werkzeuge or consult the technical advisors for specification matching.

Hexagon nut DIN 6330B M14 — high-strength fastening, 21 mm across-flats (AMF)

The Hexagon nut DIN 6330B M14 provides a standardised, high-strength fastening solution for mechanical assemblies, maintenance and machine construction where secure bolted connections are required.

• Strength class 10 for high clamping force
• Complies with DIN 6330B standard
• 21 mm across‑flats for secure wrenching

Robust performance for demanding bolted joints

The fastener is specified to DIN 6330B and manufactured to deliver reliable mechanical behaviour under load. With a nominal thread of M14 and strength class 10, the component offers superior clamping capacity compared with lower grades, which reduces the risk of loosening in dynamic applications. The standard conformity simplifies selection and quality assurance processes in industrial procurement and supports predictable assembly behaviour in production environments.

Precise geometry for correct tool engagement and assembly

Measured dimensions such as 21 mm across‑flats and an overall height of 21 mm ensure compatibility with common spanner and socket tools, improving assembly speed and torque transmission. The listed corner width of 23.40 mm provides the geometric context for handling and clearance calculation in tight assemblies. These precise measures make inventory management easier and reduce downtime caused by mismatched tooling or incorrect fastener choices.

Simplified sourcing and traceability for workshop supply chains

Marked with the AMF designation and the SKU, the component integrates into standard procurement and storage routines. The compact packaging unit (1) is suitable for targeted replacement tasks and small-batch maintenance orders. Clear standardisation, visible on the fastener, supports traceability and documentation in quality systems and helps reduce the administrative overhead when specifying replacement or spare parts for production lines.

FAQ

What does DIN 6330B signify for this fastener?
DIN 6330B denotes the dimensional and geometric standard to which the hexagon nut conforms, ensuring that the Hexagon nut DIN 6330B M14 fits and functions with mating parts produced to the same norm.

How does strength class 10 affect application?
Strength class 10 indicates a high-strength grade; the AMF hexagon nut with this rating provides greater clamping capability than lower classes, making it suitable for joints subject to elevated stresses.

Which spanner or socket fits this nut?
A 21 mm across‑flats dimension requires a 21 mm spanner or socket for correct torque application to the M14 hexagon nut (SKU 4000833396NW).

Is the overall height relevant for installation?
Yes, the overall height of 21 mm influences thread engagement depth and clearance calculations; this geometric data assists in specifying compatible bolts and washers for secure assemblies.

What is the packaging unit and how is it supplied?
The item is supplied in a packaging unit of 1, enabling single-part replacement and controlled procurement for maintenance tasks.
