Stud bolt DIN 6379 M16 x 250 mm, tempered to 8.8 — AMF

A Stud bolt DIN 6379 M16 x 250 mm tempered to 8.8 (AMF) for secure, standardised mechanical joins in workshop and industrial applications

• Conforms to DIN 6379 standard
• M16 thread for robust connections
• Tempered to strength class 8.8
• Hex drive width 19 mm for controlled torque

Consistent performance for structural fastenings

Conformity with DIN 6379 guarantees that this stud bolt fits established machine and assembly standards, which simplifies spare-part management and reduces downtime. The M16 thread paired with the 250 mm overall length provides a long engagement depth that is suitable for bolting through thick assemblies, while the tempered treatment to class 8.8 increases tensile strength and yield characteristics. This combination is designed for repeatable clamping force, which helps maintain joint integrity under cyclic loads and routine maintenance.

Precision features that aid efficient installation

The external thread form and the hex 19 mm drive interface enable reliable torque transmission during tightening, so the joint can be tensioned predictably. These characteristics, when used with calibrated torque tools, reduce the risk of over- or under-tightening and contribute to consistent assembly quality. The item’s adherence to an established norm allows planners to specify the fastener in CAD and parts lists with confidence, facilitating procurement and ensuring compatibility across production batches.

Clear specification and supply details for purchasing

Technical transparency is provided through the clear labelling of standard, thread size and strength class, which streamlines material approvals and quality checks. The product is supplied as a single unit, labelled for traceability and inventory control. The SKU 4000833277NW and the visible marking of 8.8 tempering support documentation for quality records, and purchasing teams benefit from immediate identification when ordering replacements or matching components.

FAQ

What does strength class 8.8 mean for load capacity?
Strength class 8.8 indicates a quenched and tempered bolt with enhanced tensile and yield properties compared with lower classes; the AMF stud bolt graded 8.8 is intended for demanding mechanical joints where reliable clamping is required.

Is this stud bolt compatible with metric nuts and standard components?
Yes, the Stud bolt DIN 6379 M16 x 250 mm tempered to 8.8 (AMF) is made to the DIN 6379 specification and is compatible with standard M16 nuts and mating parts manufactured to the same norm.

How should the bolt be tightened to achieve correct clamping?
Use a calibrated torque or tensioning tool and apply the manufacturer-recommended torque for M16 threads and strength class 8.8; controlled torque ensures the AMF stud bolt achieves the intended preload without overstressing the assembly.

What is delivered in one packaging unit?
Packaging unit 1 contains one AMF stud bolt, clearly labelled with SKU 4000833277NW for inventory and quality-traceability purposes.
