I found two of these in one of my parts boxes today. They are
identical except for numbers. The first one (if we are talking
ascending order) has 2727 then a diamond with FP in it then the number 1

The second has 2727 then a diamond with FP in it then the number 2

The centre of #1 has 87 in it. The centre of #2 has 88 in it.

Both have 333854 on the other side of the raised ring.
The rings appear to be raised in the middle with the outside lower but
they are actually recessed in the middle, like something could stand
in them or the could go on the end of something??

They are a lightweight metal of some sort. Clank when touched together.

I cannot work out what they are/do/are used for.

Any ideas?


Not knowing their size, I could be wrong but it looks like they might be used
on a transom for a small outboard motor's threaded clamps with the pivoting
washer on the end to fit into so it doesn't mar the GRP??


They would certainly fit the bill for that purpose. Maybe I should use
them for that and stop cutting into the resin board I have?
I can't see why a manufacturer would go to the trouble of numbering them
just for that, though.
