DIN 6303 is a standard that defines a knurled nut used for fastening parts. This nut has a toothed profile on the inner surface that provides a grip on the bolt or stud that resists loosening. DIN 6303 knurled nut is a metric nut with an internal thread that has a curved surface on the outside of the nut. This curved surface, known as a knurl, helps to increase the nut's resistance to reverse rotation because it provides additional friction between the nut and the surface it is in contact with.
Materials used to manufacture DIN 6303 nuts
DIN 6303 nuts are made of steel, which is additionally coated with zinc.
Areas of application for DIN 6303 nuts
These nuts are used in various industries, construction and automotive to ensure reliable fastening of parts. They can also be used to prevent loosening of nuts subjected to vibration or external stress.
Knurled nuts are used in a variety of industries where it is important to provide a secure connection and prevent the nut from self-passing due to vibrations or other external factors. For example, they are often used in the transportation industry, metalworking industry, construction industry, machinery industry, and other industries where a strong connection is required.
