Stud bolt DIN 6379 M20x80 mm — heat-treated to 8.8, AMF

A Stud bolt DIN 6379 M20x80 mm designed for secure, repeatable fastening in machinery and equipment where standard conformity and predictable mechanical behaviour are required.

• DIN 6379 standardised geometry
• Property class 8.8, heat‑treated
• Thread M20 for metric assemblies
• Overall length 80 mm, shank b = 32 mm

Reliable strength for medium‑duty fastening tasks

Manufactured to DIN 6379, the fastener delivers consistent form and fit, while the 8.8 property class denotes a heat‑treated component suited to medium‑duty connections. Such classification ensures a dependable balance between tensile strength and ductility, which reduces the risk of unexpected failure under typical assembly loads. The result is a fastener that supports predictable performance in recurring maintenance and production environments, lowering downtime and rework.

Predictable fit and easy installation with metric standards

The M20 metric thread and the defined shank dimension b = 32 mm provide compatibility with common nuts and threaded holes used across industrial applications. Compliance with the DIN specification simplifies procurement and assembly planning because mating parts can be selected with confidence. The clear geometric definition reduces assembly variability, shortens installation times and supports consistent torque application during tightening.

Practical logistics and assured sourcing for workshops

Supplied by the brand AMF and offered as an individual unit, the component is suitable for replacements and small batch assemblies where single items are required. Sourcing via Metav Werkzeuge benefits from a European quality filter and centralised stock management, enabling reliable supply to workbenches and workshops. The SKU and standard reference help to integrate the component into inventory systems and maintenance lists for streamlined operations.

FAQ

Does this fastener conform to a recognised standard?
Yes. The item is produced in accordance with DIN 6379, ensuring standardised geometry and interchangeability for metric assemblies.

What does property class 8.8 indicate for the stud bolt?
Property class 8.8 means the fastener is heat‑treated to provide elevated tensile strength and yield characteristics suitable for medium‑duty fastening tasks where reliable mechanical performance is required.

What are the key dimensions to check for compatibility?
Key dimensions are M20 thread, overall length 80 mm, width 27 mm and a shank section b = 32 mm; reference the SKU 4000833282NW when cross‑checking mating parts.

Is the component sold individually or in bulk?
This item is supplied as a single unit (packaging unit: 1), which is practical for replacement parts or small assembly runs.

Can the stud bolt be used in machinery and equipment assemblies?
Yes. The combination of standard conformity and property class makes it suitable for many machinery and equipment fastening applications; however, specific load and safety calculations should follow the relevant engineering guidelines.
