Stud bolt DIN 6379 M12×50, tempered to property class 10.9 (AMF)

Stud bolt DIN 6379 M12×50 is a high-strength fastener for mechanical and structural applications, offering standard metric thread engagement for consistent clamping performance

• Tempered to property class 10.9
• Conforms to DIN 6379 standard
• Metric thread M12 for interchangeability
• Overall length 50 mm for defined engagement

Reliable high-strength fastening for industrial assemblies

The AMF stud bolt, manufactured to DIN 6379, delivers predictable mechanical performance thanks to its tempering to property class 10.9, which indicates elevated tensile and yield strength compared with lower classes. In practical terms, this means the fastener sustains higher clamping loads and resists permanent deformation in demanding joints. For procurement and engineering teams the clear benefit is a fastener that supports safety margins without oversizing components, reducing redesign effort and maintaining production throughput through dependable mechanical behaviour.

Standard compliance and assembly compatibility

Compliance with DIN 6379 and the use of a standard M12 thread ensure straightforward integration into metric assemblies and compatibility with commonly stocked nuts, washers and tapped holes. Specifying this fastener reduces variability in component sourcing and simplifies inventory management for maintenance and production. The standardised geometry also aids automated assembly processes, as tools and torque settings can remain consistent across batches, improving cycle times and lowering risk of assembly errors.

Durability that supports long service intervals

Tempering to property class 10.9 provides enhanced fatigue resistance and dimensional stability under cyclic loading, which benefits installations subject to vibration or fluctuating loads. The controlled heat treatment process yields uniform mechanical properties that translate into longer maintenance intervals and fewer unscheduled stoppages. Combined with AMF’s manufacturing standards, the result is a robust fastener option for machinery, frames and structural connections where reliability is a priority.

Practical application guidance for designers and fitters

The stud bolt is supplied in a single-piece packaging unit, suitable for controlled assembly procedures and traceable component usage. When integrating the fastener into a joint, match thread class and mating materials, apply the manufacturer-recommended lubrication and tightening procedure, and verify clamp loads according to the joint design; this approach preserves the 10.9 property-class performance. For special applications or unusual material combinations, technical consultation is recommended to confirm suitability and torque settings.

FAQ

What strength class does this stud bolt have and what does it mean?
The stud bolt is tempered to property class 10.9, which indicates high tensile strength and good yield characteristics suitable for demanding mechanical joints.

Is the thread specification compatible with standard metric nuts?
Yes, the M12 thread conforms to metric standards and is compatible with standard M12 nuts and tapped holes when matched by thread class.

For which applications is this DIN 6379 stud bolt most suitable?
This fastener is suitable for mechanical assemblies, structural connections and equipment subject to elevated loads or dynamic stresses where property class 10.9 performance is required.

How long is the stud bolt and how does that affect engagement?
The overall length is 50 mm, providing defined thread engagement; designers should verify that this length matches the required clamping and thread engagement for the joint.

Can the fastener be used with hardened or specialised materials?
Use of the stud bolt with hardened or specialised mating materials should be reviewed for compatibility; consult the technical documentation or Metav Werkzeuge for joint-specific guidance.
