measure of stratocaster bridge plate screws

[josesrv]

I need to replace the three screws that holds the block to the bridge plate on an american made stratocaster so I want to know which is the correct size/measure and or thread of these screws , and if I can buy them from any supplier that fits the usa vintage blocks.
PS: Do the Gotoh stuff (screws) fit on the american made blocks?
Many thanks.
