Happy with what I bought these for
Not sure what these are meant for but screws were too long on a bedside cabinet so used these rather than sawing the screws down. Worked perfectly.

Very very thin
These are extremely thin they are not much bigger than the M4 screws that go through them. I dont feel comfortable mounting anything with these.

These standoff washers are ideal. Check for size
I wanted these to lift my tilting bucket raingauge off the ground by a centimetre and these have done the job perfectly. They are made of quite hard material and feel more like ordinary plastic but are supposed to be nylon.
