DIN 127-A refers to a type of washer used to prevent fasteners from loosening on their own. The spring washer is one type of stainless steel washer. Other names you may encounter in everyday life include “grover washer” and “grover.”

These washers come in two shapes: Type A and Type B. Type A washers are distinguished by their curved (downward-sloping) ends. These washers grip the surface more effectively, thereby preventing self-loosening. They can also be used in environments with high vibration or heavy loads.

Applications: mechanical engineering, metal structures, solar energy, automotive industry.

Material: steel.

Coating: hot-dip galvanized. Hot-dip galvanizing protects against corrosion when fasteners are intended for use in harsh environments.
