Stiftschraube DIN6379 M20x500mm, tempered to 8.8 — AMF stud bolt for heavy-duty fastening

Stiftschraube DIN6379 M20x500mm vergütet auf 8.8 AMF is a long M20 stud bolt designed for secure mechanical joins and through-bolting in structural and machine-building applications.

• DIN 6379 conformity
• High-strength grade 8.8 tempering
• M20 thread for heavy-duty fastening
• 500 mm overall length

Predictable assembly with standard compliance

Conformity to DIN 6379 guarantees dimensional interchangeability and consistent thread geometry, which simplifies procurement and replacement planning. For production lines and maintenance workshops, a standardised fastener reduces measurement effort and tolerance checks; the clear reference to the norm also aids documentation and quality control. The certified specification contributes to reliable joint behaviour under dynamic load and supports traceability across components.

Strength and safety from grade 8.8 tempering

Tempering to grade 8.8 provides improved tensile and yield properties compared with general-purpose fasteners, resulting in a more secure clamped joint and lower risk of deformation in service. This fastener's heat treatment enhances fatigue resistance for cyclic loads in rotating or vibrating equipment. For engineers and buyers, the benefit is fewer unscheduled maintenance stops and extended service intervals owing to the improved mechanical performance.

Long reach design reduces installation complexity

With an overall length of 500 mm, the stud bolt is suitable for deep or sandwich-type assemblies where through-bolting is required. The extended length eliminates the need for multiple components or extensions, streamlining inventory and minimising assembly steps. The M20 thread dimension is a common size in heavy machinery, ensuring compatibility with standard nuts and washers and easing integration into existing assemblies.

Manufactured for consistency and reliable supply

Produced under the AMF label, the fastener is made to the declared standard and labelled for clear identification. Sourcing through Metav provides an additional quality filter and logistical reliability from the Emmerich location, which is particularly valuable for industrial users who require consistent replenishment. The combination of defined manufacturing practice and dependable delivery reduces administrative overhead and supports uninterrupted production.

Practical benefits for procurement and maintenance

Specifying this stud bolt simplifies purchasing lists and maintenance kits: the clear designation, known thread size and tempering class enable straightforward selection and stock control. Maintenance technicians and assembly planners benefit from fewer part variants and direct compatibility with common tightening tools and torque tables. Where traceability matters, the SKU and labelling help link installed parts to batch records.
