Round nut with holes | A1 | DIN 547

Round nut with two holes in A1 is intended for use in mechanical and industrial applications where axial locking and secure fastening are required. The product complies with DIN 547 and is used where low installation height or limited assembly space makes hexagonal nuts less suitable. The two holes in the nut are used for mounting and dismounting with a hook spanner or pin wrench. The nut is suitable for technical installations where precise assembly and reliable function are crucial.

AREA OF APPLICATION

The product is used in the machine industry, shaft assembly, transmission solutions, and mechanical constructions. It is intended for applications where axial fixation is required and where the material choice provides the necessary protection against corrosion and mechanical stress.

FREQUENTLY ASKED QUESTIONS (FAQ)

What are the holes in the nut used for?
The holes are used in conjunction with a hook spanner or pin wrench to tighten or loosen the nut during assembly and disassembly.

When is a round nut used instead of a hexagonal nut?
Round nuts are often used where limited assembly space or low installation height is required, for example in shaft assemblies and bearing mountings.

What does DIN 547 mean?
DIN 547 is the standard for round nuts with two holes intended for mechanical fastenings and axial locking.

Is A1 stainless steel corrosion-resistant?
Yes. A1 is stainless steel with good corrosion resistance for dry and normal indoor environments.

Which tools are used for assembly?
The nut is normally installed with a hook spanner or pin wrench adapted to the hole dimension and nut size.
