Carb float bowl screws?
 

Need the 4 screws with washers that hold the float bowl on as mine are rounded of badly anyone know where i can get a set as from dealer there about ?1.50 per screw and they charge ?4 to post plus i have to use card over phone and give details ect and i have no time as i work all during there open hours.

Try the local hardwear store. there metric size ,sorry cant help further w/ pitch etc.

Just go to a hardware/fasnteners store and get some allen heads to replace them. Can't recall the thread size, but they are standard (maybe M4).

I think they are 4mm.
there is only one pitch, as far as i know.
i used allen head stainless steel with lock washers

4mm x .70 pitch 12 or 14mm long

FYI. For the Keihin OEM float bowl screws, you will need a PoziDrive screwdriver. Not phillips.;)
