AMF Stiftschraube DIN 6379 – Stud bolt M20 x 200 mm, property class 8.8

The AMF Stiftschraube DIN6379 M20x200mm is a heat‑treated stud bolt designed for secure fastening in industrial and workshop assemblies.

• DIN 6379 conforming stud bolt
• Heat-treated to property class 8.8
• Thread M20 for standard fittings
• Overall length 200 mm

Reliable fastening for demanding assemblies

A stud bolt manufactured to an established metric standard delivers consistent clamping and repeatable performance. The compliance with DIN 6379 ensures dimensional accuracy and interchangeability with standard nuts and threaded components, reducing assembly time and the risk of mismatched parts. Specifying a stud with defined mechanical properties supports predictable joint behaviour under load, which in turn helps to minimise unscheduled downtime and keeps production flows steady.

Clear specification for confident selection

Key specification data such as M20 thread and 200 mm overall length make selection straightforward when matching to flanges, housings or repair parts in mechanical systems. The marking of property class 8.8 indicates that the fastener has been heat‑treated to provide elevated strength compared with standard grade fasteners; this attribute is important when higher clamping forces or fatigue resistance are required. Where necessary, refer to the relevant engineering tables or DIN documentation for pitch and torque guidance to ensure secure installation.

Practical fit and installation guidance for workshop use

For routine workshop and industrial use, this stud bolt works well in assemblies that demand a robust metric connection and consistent geometry. When installing, ensure correct thread engagement and use appropriate locking measures to maintain joint integrity over time. The product’s standardised dimensions facilitate inventory management and simplify maintenance planning, enabling rapid replacement during service operations and supporting efficient workshop workflows.
