Stud screw DIN 6379 – M16 x 80 mm, heat-treated to property class 8.8 (AMF)

Stud screw DIN 6379 – M16 x 80 mm, heat-treated to property class 8.8 (AMF) is a purpose-made fastener for load-bearing machine and structural joints, specified to DIN 6379 for repeatable mechanical performance

• DIN 6379 compliant design
• Heat-treated to property class 8.8
• M16 thread with 80 mm overall length
• Across-flats tool engagement 19 mm

Reliable clamping performance for industrial assemblies

The stud screw is manufactured to DIN 6379, delivering a predictable combination of tensile and yield strength thanks to the heat-treated finish at property class 8.8. This material treatment increases load capacity while maintaining ductility, which helps prevent sudden brittle failure in cyclic or dynamic applications. In practice, that means the fastener sustains higher preloads and resists relaxation under vibration—attributes that promote longer service intervals and fewer rework cycles in production lines and maintenance schedules.

Clear specification for correct component selection

Critical specifications are immediately usable for procurement and engineering documentation: M16 thread, 80 mm overall length and a spanner engagement of 19 mm indicate the intended mating hardware and tool sizes. The part is listed under SKU 4000833272NW and packaged as Packaging unit 1, which simplifies traceability and inventory management. Specifying the fastener by these data points reduces the risk of ordering mismatched items and supports consistent assembly quality across batches.

Efficient workshop handling and installation

The combination of standard thread sizing and a conventional across-flats dimension enables rapid installation with common workshop tools, reducing downtime during assembly or repair. Because the component adheres to a recognised DIN standard, it integrates smoothly into existing bills of materials and quality checks. The result is improved shop-floor throughput and fewer interruptions caused by atypical fasteners, supporting a leaner workflow in both manufacturing and maintenance contexts.

Suitable applications and material compatibility

Designed for general steel construction, machinery assembly and repair work, this stud screw is a pragmatic choice where a reliable threaded connection is required. The AMF designation denotes the brand origin; the fastener’s heat treatment to 8.8 offers a suitable balance for medium-duty structural tasks. Where higher hardness classes or corrosion resistance are necessary, selection should be guided by specific environmental and mechanical requirements to ensure optimal longevity.
