Stiftschraube DIN6379 M20x160mm, tempered to 8.8 — AMF stud bolt

A stud bolt DIN 6379 M20x160mm engineered for high-strength joining in mechanical and structural assemblies, particularly where standardised dimensions and reproducible performance are required

• High tensile class 8.8
• Standard DIN 6379 compliance
• Thread size M20 for common fittings
• Spanner width 27 mm for secure tightening

Reliable strength and repeatable performance for industrial assemblies

The combination of DIN 6379 geometry and a Class 8.8 heat treatment delivers a predictable yield and tensile behaviour that supports safe connections under cyclical and static loads. Specified as a stud bolt with a metric M20 thread and 160 mm overall length, this component provides a consistent fit in standard nuts and tapped holes. The material is tempered to achieve the stated strength grade, which reduces the risk of elongation or failure in service and simplifies engineering calculations for joint design. For production environments that prioritise uptime, the standard compliance reduces inspection overhead and supports interchangeability across suppliers.

Practical benefits during installation and inspection

A defined spanner width of 27 mm and an overall design to DIN 6379 make handling, torqueing and visual inspection straightforward. The uniform thread profile ensures predictable torque–tension relationships, easing the selection of tightening procedures and torque settings in assembly instructions. The fastener’s geometry supports use with standard fastening tools and common nuts, enabling efficient assembly lines and clean maintenance protocols. Traceability is simplified when components adhere to established standards, which helps quality control teams document batches and perform acceptance checks with confidence.

Application suitability and lifecycle considerations

Designed for applications requiring medium-high strength, the stud is suitable for machinery frames, fixture assemblies and structural joints where M20 metric fasteners are standard. The Class 8.8 rating indicates good resistance to standard mechanical stresses encountered in industrial and workshop settings while remaining compatible with commonly used steels and fittings. For environments with special corrosion or temperature demands, material and coating requirements should be verified separately; this fastener’s documented standard and grade provide a clear baseline for such assessments and for specifying any additional surface treatments or specialised grades if needed.

FAQ

Is this stud bolt suitable for structural bolting applications?
The stud bolt specified to DIN 6379 and tempered to Class 8.8 is suitable for many structural and mechanical joining tasks where medium-high strength is required; check the joint design and loading conditions to confirm suitability.

What are the key dimensions to check before ordering?
Verify the M20 thread size, the overall length of 160 mm, and the spanner width of 27 mm to ensure compatibility with mating nuts and clearance in the assembly.

Can the fastener be used with standard metric nuts?
Yes — the M20 metric thread is compatible with standard M20 nuts specified for the corresponding strength class, provided the nut grade and fit match the application requirements.

How is the strength grade indicated and what does Class 8.8 mean?
Class 8.8 denotes a quenched and tempered steel with a defined yield and tensile strength range; the designation indicates medium-high tensile performance suitable for many industrial applications.
