Flat Washers - Metric - Form A

Form A is the most commonly used type of metric flat washer and they are available in a wide range of sizes and finishes. They are commonly used with hex nuts, machine screws and socket screws as well as many other types of fasteners.

The main purpose of a flat washer is to spread the force that is created by the tightening of a nut across a wider surface area.

Flat washers are also occasionally used as spacers, they are useful for this purpose if the bolt being used is slightly too long for the application in question.

If you need a washer with a slightly larger diameter than a Form A, we suggest you try a Form C. If you need a washer that is larger still then choose a repair washer.
