there are a few types of washer but standard washers are generally used to distribute force and to help stop the fasteners working loose. Having said that if your fasteners are too long washers make ideal spacers. Washers also make fastened items look more appealing.

Have any of you ever worked on an actual IC engine? This is absurd!!

Such an engine would produce power only once in 3 crank revolutions. It would require a huge flywheel simply to keep it moving during the remainder of the time.

If this was a viable idea, why do you think it is not already in production? Someone would have already done it, except that it does not work well at all.

To protect the bolt hole, spread the load & forces evenly,  as a spacer, protect the nut from crevice & galvanic corrosion.

Sir what is crevice and galvanic corrosion

My comment above, quoted by Pandit Shivam shukla, is in the wrong discussion and should be disregarded. I'm not sure how it got here. It was intended for a thread related to a six stroke engine, if I recall correctly.

I regret the error in this posting.

The washers provides a hard flat and smooth surface for the nut and head of the bolt to slide on. If the nut or bolt turn and the component is a soft material a lot of the torque applied may be absorbed by the displacement of material and not provide as much tensile load as expected. Also spreading the force over a greater area, bridging the gap between the bolt and a oversized hole. There are many types of washer for different applications.

It is used to tighten the nut enough so that  there is no leakage.....in case of lubricating system.....or to maintain a grip of the nut so that during any shocking movement or up..down....movement.....👌👌👌👌👌👌

Washers are used to increase the tightening strength of a material (bolt and nuts),prevent a bolt and nut from playing in the material etc
