Washer DIN 988-PS M20x28x1 A2

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 usually installed in conjunction with circlips. 

DIN 988-PS (spring effect washer) is a washer that provides elasticity in a joint, helping to compensate for loads, vibrations and displacement of parts. It is used to adjust the height and ensure the stability of a joint under mechanical stress without requiring sealing.

Application: DIN 988-PS has a place in areas such as machine tool, instrumentation and manufacturing industries. It is mainly used to compensate for axial clearances of machine parts.

The material of manufacture: is stainless steel. Steel grade A2 allows the fastener to be used at high temperature extremes and in aggressive and humid environments.

Coating: Uncoated.
