How is this part called in english?
(OP)
Hi everyone,
My name is Martin, I am new here. I signed, because I really need help with finding the correct english name for a certain part.
Please take a look at the following two pictures:

These are both cradles for marine chartplotters. What I need identified, are the faceted washer-like parts, that (when tightened) lock the chartplotter into a fixed position. In this type of assembly, when you loosen the nuts, you can adjust the angle of the screen. Once you are happy with the angle, you tighten the assembly, and those faceted washers lock it into the desired position.
So what do I need this for? I am trying to design an LED street lamp, and I need to make the lamp holder with adjustable angle. And these parts would really help me.
I've been googling for friction washers, locking washer and stuff but that is just not the correct name for this.
I need to find the proper name, so I can search for the right part (I can not obtain it locally, I need to order it from the internet).
I would really appreciate any help on this matter.

RE: How is this part called in english?
That is why I need those finely faceted washers/pads. With one on each end of the assembly, they should be able to withstand all loads.
Edit: I found these in Google:
http://halfinchrails.com/wp-content/uploads/2012/0...
Here they call them "serrated pair", but I can not find any more results in google.
Now these are exactly what I need. Now I just need to find some catalogue with different sizes.
Does anybody know any other names for these?

I can mill those serrated washers out of 3 or 4 mm aluminum sheets. But I am afraid the fine teeth will quickly flatten. I do believe that those washers/pads should be made from steel.

> how often does one adjust a street lamp? if it's more than once a year, I'd be surprised
> in order to actually move the lamp, the washers have to clear each other, so wear should be minimal
In any case, see below for alternatives

RE: How is this part called in english?
I will try to mill them out of sheet aluminum and see what happens.

and in particular am wondering if you are seeking their "wedge-lock washers"

I really didn't think that these:
would really be so hard to identify and obtain.
So far, I think that my best bet would be to try to mill them with a 0.5mm V-shaped tool.

How about serrated locking plates?
