AMF Hexagon Nut M14 (DIN 6331) — SW 22, Strength Class 10, Pressed and Milled

The AMF Hexagon Nut M14 (DIN 6331) is a high-strength fastening element designed for industrial assemblies where standard conformity and repeatable clamping force are required.

• Hexagon nut M14 to DIN 6331 specification
• Strength class 10 for high clamping loads
• Spanner width 22 mm, corner size 24.5 mm
• Pressed and milled finish, overall height 21 mm

Engineered for dependable clamping performance

The design follows DIN 6331, which guarantees thread and form compatibility with standard bolts and reduces the risk of joint failure in production environments. With strength class 10, the component is rated for elevated tensile and yield limits, so assemblies subject to dynamic or high static loads can be calculated with confidence. The metric M14 thread is a common industrial dimension; its predictable load-bearing behaviour simplifies selection for fixtures and structural joints. This results in fewer rejects and a more stable production process when the correct tightening procedures are applied.

Precision geometry that simplifies assembly and maintenance

A defined spanner width of 22 mm and a corner size of 24.5 mm ensure consistent engagement with conventional tools, reducing the chance of rounding and tool slippage during torqueing. The pressed and milled finish produces flat seating faces and accurate flank contact, which lowers stress concentrations and improves clamping distribution. The overall height of 21 mm provides sufficient thread engagement for standard bolts, enabling reliable torque transmission while retaining accessibility for maintenance operations. Such geometry is particularly beneficial where reproducible torque is required across multiple joints.

Application scope and practical benefits in workshop and industrial use

The component is suitable for bolted joints in machines, jigs, and structural assemblies where standardised parts are preferred for interchangeability. Compliance with DIN 6331 facilitates procurement and quality control, since the fastener can be inspected against recognised tolerances. Supplied individually (packaging unit 1), the item is convenient for replacement tasks or small-batch assembly. For customers requiring additional verification, technical documentation and specification checks can be provided to match the nut to bolt grade and application-specific torque charts, supporting safe and efficient engineering decisions.

FAQ

What load class does this nut meet and why does it matter?
The AMF hexagon nut is specified as strength class 10, which indicates higher tensile and yield properties suitable for assemblies subject to elevated clamping forces; this allows safer design margins where stronger bolted joints are required.

Is the nut compatible with standard M14 bolts to DIN specifications?
Yes, the item conforms to DIN 6331 and is dimensioned for M14 threads, ensuring interchangeability with bolts produced to the same standard.

Which spanner size is required for assembly?
A spanner width of 22 mm is required; the corresponding corner size is 24.5 mm, which supports secure tool engagement and consistent torque application.

How does the pressed and milled finish affect performance?
The pressed and milled finish yields accurate seating faces and reduced form deviation, which improves load distribution and lowers the potential for fretting or uneven clamping in long-term service.

Can the nut be used for high-vibration applications?
Given the strength class 10 rating and precise geometry, the nut is suitable for applications with dynamic loads when combined with the correct bolt grade and appropriate locking methods.
