DIN 127 B Helical Spring Washer – Steel

Split helical spring washer manufactured from steel, with geometry corresponding to the traditional DIN 127 form B reference.

Its shape produces an elastic reaction when compressed during tightening. It is mainly used as a replacement part in existing assemblies or in conventional mechanical applications originally designed for this type of washer.

Main features

• Split helical washer with flat ends.
• Steel construction.
• Traditional DIN 127 B geometry.
• Available for M3, M4, M5, M6 and M8 metric fasteners.
• Particularly suitable for maintaining assemblies already using this component.

Nominal dimensions

Nominal reference values for a DIN 127 B washer. Free height is measured without compression, and manufacturing tolerances may apply.

Important assembly considerations

DIN 127 B is a historical specification that has been withdrawn. Although these washers are still widely used as replacement components, they must not be
