AMF stud bolt DIN 6379 — M24 × 400 mm, property class 8.8

A AMF stud bolt DIN 6379 M24 x 400 mm, heat-treated to property class 8.8, designed for secure bolted connections in mechanical and structural assemblies

• Stud bolt to DIN 6379 standard
• Heat-treated to property class 8.8
• M24 metric thread for high-strength fastening
• 400 mm overall length for deep assemblies

Engineered for dependable, high-strength joints

The stud is manufactured to the DIN 6379 specification, ensuring repeatable geometry and compatibility with standard M24 components. Heat treatment to property class 8.8 provides defined mechanical properties and improved fatigue resistance compared with untreated fasteners. These characteristics translate into consistent clamp force and reduced risk of connection loosening in demanding applications, supporting predictable maintenance intervals and reliable operational uptime.

Dimensions and thread form that speed up assembly

With an M24 metric thread and an overall length of 400 mm, the stud is suitable for deep fittings where standard-length fasteners are insufficient. The long engagement length enables secure thread engagement without extensions, while compatibility with standard M24 nuts and washers simplifies procurement and reduces the number of bespoke parts required. The result is a leaner assembly process with fewer handling steps and less downtime during installation.

Proven quality and supply continuity for workshops

Produced by a recognised industrial supplier and offered through Metav’s distribution, the fastener is intended for industrial and workshop environments where traceability and consistent quality matter. Sourcing via a supplier with a quality filter in Emmerich supports steady availability and batch consistency. The component’s specification and conformity to standards help maintain safety margins in structural and mechanical joints, offering long-term confidence in both new builds and retrofit projects.

FAQ

What does property class 8.8 mean for the stud bolt?
Property class 8.8 indicates a heat-treated steel fastener with elevated mechanical properties; the AMF stud bolt in property class 8.8 is designed for higher tensile and yield strength than non-heat-treated equivalents, suitable for structural and mechanical load-bearing joints.

Is this stud bolt compatible with standard M24 nuts and washers?
Yes, the stud has an M24 metric thread and is designed to mate with standard M24 nuts and washers for conventional fastening arrangements.

For which applications is the 400 mm overall length intended?
The 400 mm overall length suits deep assemblies and situations where extended thread engagement is required, such as long flanges, stacked components or retrofits that exceed standard fastener lengths.

Does the product conform to any recognised standard?
The fastener complies with DIN 6379, providing standardised dimensions and tolerances for use in industrial and workshop applications.

What information does the SKU 4000603368NW provide?
SKU 4000603368NW uniquely identifies this AMF stud bolt variant (M24 x 400 mm, property class 8.8) for ordering and inventory tracking purposes.
