Dimensions of the DIN125A M5 washer

The designation 5.3 x 10 x 1.0 stands for the inner diameter, outer diameter and thickness in millimeters. The inner diameter of 5.3 mm gives the bolt just enough clearance to pass through smoothly. The outer diameter of 10 mm determines the size of the bearing surface, and the thickness of 1.0 mm determines how sturdy the washer itself is.

Galvanized (ZN) and 140HV: what does that mean?

ZN stands for a zinc layer on the steel. This layer provides basic protection against rust, especially suitable for dry indoor environments. For outdoor applications or damp spaces, it is advisable to check whether a zinc layer is sufficient, or whether another version, such as stainless steel, is more suitable. The value 140HV is the hardness class of the washer, expressed in Vickers.

Which washer do you choose for an M5 connection?

First look at the bolt size: an M5 bolt requires a washer with a hole of 5.3 mm. Then consider the material you are fastening to. For soft materials such as wood or plastic, a washer with a large outer diameter helps prevent indentation. Preferably combine the washer with bolts, screws and nuts in the same coating, so that the finish of the entire connection is uniform.
