Washer DIN 988-SS M20x28x2

An adjusting washer is a fastener that, unlike the main type of washers, has a very narrow field and a wide range of thicknesses for each diameter. For example, with a diameter of 5 mm, we will have a set of washers with a thickness of 0.1 to 1 mm, in increments of 0.1. This allows you to perform the main function of this washer - to adjust the gaps between the elements to be connected and the fastener to balance the assembly and avoid skewing or backlash, with an accuracy of 0.1 mm. This makes the connection more reliable as it reduces vibration forces. This washer is mostly used in conjunction with circlips. 

DIN 988-SS (washer with sealing effect) - this washer has an additional sealing function to ensure a tight connection. It combines the functions of gap adjustment and sealing and is therefore used in joints where not only stability but also sealing is important.

DIN 988-SS is used in areas such as machine tool construction, instrumentation and manufacturing. It is mainly used to compensate for axial clearances of machine parts.

The material of manufacture: is steel. 

Coating: Uncoated.
