Product Type

DIN 6798 A: External Serrated Washers The serrated exterior of the washer may prevent the nut or bolt from loosening due to increased friction with the surfaces of the connected parts.
DIN 6798 J: Internal Serrated Washers The washer has serrations on the inside to prevent the screw from loosening and is suitable for screws with smaller heads.
DIN 6798 V: Commonly used for countersunk screw installations, the shape of the countersunk V-type washer matches the screw to improve stability and locking.

Locking washer material

Common materials for producing washers include stainless steel 304, 316 and spring steel. Different materials have different characteristics and can be selected according to the specific use environment and requirements.

Stainless steel 304: has good corrosion resistance and is suitable for general environmental conditions, such as indoors and at room temperature.

Stainless steel 316: has better corrosion resistance than 304, especially in environments containing corrosive media such as chloride ions, and is often used in harsh environments such as oceans and chemicals.

Spring steel: has high elasticity and toughness, can compensate for the deformation of the connection to a certain extent, and provide a more stable locking force.
