Proven strength for industrial fastening

The fastener is manufactured to DIN 6379, ensuring dimensional consistency and interchangeability across assemblies. With a M6 metric thread and an 80 mm overall length, the component delivers predictable engagement depth and reliable load distribution. The specified Grade 8.8 tempering indicates a high tensile strength and improved fatigue resistance, making the fastener suitable for repetitive load cycles in production and maintenance environments. This combination reduces downtime by lowering the risk of premature failure and simplifies procurement through standard conformity.

Practical compatibility and installation advantages

Compatibility with standard metric tooling and thread tolerances reduces set-up time on the shop floor. The stud’s metric thread enables straightforward integration with tapped holes, nuts or coupling components commonly used in mechanical assemblies. Where adjustment or replacement is required, the standardised dimensions support rapid part matching and inventory harmonisation, contributing to a leaner spare-parts strategy. The AMF designation denotes the manufacturer label on the article, assisting traceability and supplier selection.

Durable performance and application guidance

Tempering to 8.8 enhances yield and tensile limits while preserving machinability for secondary operations where minor thread finishing may be needed. For applications demanding secure, reusable mechanical joints—such as fixture construction, machine rebuilds and conveyor supports—the hardened stud provides consistent clamping behaviour. When specifying for critical joints, pair the stud with matching grade washers and nuts to maintain the assembly’s rated strength and to avoid galvanic or mechanical incompatibilities.
