Stud bolt DIN 6379 M20×125, property class 8.8 — AMF

The stud bolt DIN 6379 M20×125 is a heat‑treated, metric threaded fastener designed for secure mechanical joins in industrial and maintenance settings.

• Conforms to DIN 6379 standard
• Metric thread M20 for common assemblies
• Heat‑treated to property class 8.8
• Overall length 125 mm for versatile use

Consistent clamping performance for machinery assemblies

The stud bolt is designed to deliver reliable clamping force where repeatable connections are required. Compliance with DIN 6379 establishes predictable geometries and tolerances, which supports consistent torque‑to‑preload behaviour in bolted joints. The M20 thread and property class 8.8 rating indicate a balance between tensile strength and ductility, reducing the risk of sudden brittle failure while enabling secure fixation under dynamic load. For procurement planners and maintenance engineers, these characteristics translate into predictable assembly behaviour and reduced rework.

Simplified installation thanks to standard dimensions

Standardised dimensions reduce complexity at the workbench and accelerate assembly cycles. The stud’s 125 mm overall length and thread specification match common nuts and clamping elements, enabling straightforward replacement in existing equipment without custom adaptations. A nominal width value of 27 mm supports compatibility with typical spanners and torque tools, so maintenance intervals can be completed faster and with conventional tooling. This dimensional clarity supports lean workshop processes and lowers downtime during repairs.

Material treatment for durability under load

The fastener is quenched and tempered to 8.8, providing strength suitable for many mechanical and structural applications while maintaining sufficient toughness. Heat treatment improves resistance to plastic deformation during tightening and service loads, which extends component life and maintains joint integrity. The construction ensures that the fastener sustains repeated assembly cycles and mechanical stresses common in industrial environments, offering a cost‑effective alternative to more exotic materials where extreme corrosion resistance or ultra‑high hardness are not required.

Procurement and quality traceability for operations

Specifying a fastener that adheres to established standards simplifies quality assurance. With the DIN reference and brand identification, batch traceability and conformity checks become straightforward steps in incoming inspection. The supplied packaging unit of 1 facilitates controlled stocking of critical spares, and the clear article identifier (SKU) supports efficient reordering and inventory management. Choosing a standardised stud from a recognised supplier minimises specification variance and supports uninterrupted production throughput.
