Where do washers go on screw?
If there is only one washer used with a nut/bolt, it usually goes on the nut side. The nut in most circumstances is more movable, and is more commonly turned to tighten the assembly. The washer helps prevent damage to the surface of the object being fastened.

If your project calls for other washers or hardware elements, they should go on before the lock washer so that it can hold them in place.
Why do you need a washer with a screw?
Threaded fasteners do a more reliable job when accompanied by washers. Most notably, washers protect the surface from damage during installation. They distribute the pressure and prevent the fastener from moving or corroding. Skipping on washers can dramatically reduce the lifespan of how your product is put together.
Why do we apply washers with screws?
Load Distribution The primary purpose of most washers is to evenly distribute the load of the threaded fastener with which they are used. Washers reduce the risk of such damage by evenly distributing the fastener’s load across the surface of the material. Not all materials require the use of washers.
What order do bolts and washers go?

Where do spring washers and flat washers go?

When should lock washers be used?
Flat washers are used to increase the surface area in order to more evenly distribute the force applied with tightening the fastener. Lock washers are used as a means of creating tension during tightening in order to help keep the nut from working loose later.
