Adjustable washer a fastening product that, unlike the main type of washers, has a very narrow field and a wide range of thicknesses on each of the diameters. For example, with a diameter of 5 mm, we will have a set of washers with a thickness of 0.1 to 1 mm, with a step of 0.1. This allows you to perform the main function of this washer - to adjust the gaps between the connecting elements and the fastener to balance the assembly and avoid skew or backlash, with an accuracy of up to 0.1 mm. This makes the connection more reliable as it reduces vibration forces. Basically, this washer is installed in a pair with retaining rings.
Scope DIN 988-PS takes place in areas such as machine tool, instrument and manufacturing industries. It is mainly used to compensate for axial clearances of machine parts.
Material stainless steel. The A2 steel grade allows you to use fasteners with significant temperature changes and in an aggressive and humid environment.
No coverage.
