whats 'table 3'?

I'm going to buy some for putting all my suspension together, found 200 for £3, which seems more tempting than 50 rose joint side spacers for £40, but i don't know what table 3 means?

You'll need a copy of BS3410 to find out the exact specifications - table 3 is the bit that defines imperial heavy gauge washers.

ah, so its a measure of how thick they are?

i need nice thick ones.

cheers Ian

They probably are, but it also describes their diameter in respect to the bolt size. And you could have thick thin or med thickness.
