That is one of the reasons I just love Canada.
We have something called a Robertson screw -- they come in all flavours from low root for decking, dry-wall, particle board right on up to machine screws and stainless steel screws for ALL applications.
YOU CANNOT MESS UP A ROBERTSON! At least not without trying real hard.
In the states they are called Square Drive..... why I don't know, maybe has something to do with being different - God only knows....
And they look real sharp! No rough edges, no scratches from screwdrivers that slip from the slotted head all over a real nice NEW paint job
I think McMaster-Carr would carry them. If not, then my buddy Dana at Maritime Fasteners does and would be more than happy to ship em south of the border
I will be using the SS Robertson machine screws for all exposed screws on Ellie - maybe even for the ones you cannot see. I too like the unpainted shiny SS look.
