BSF tools

[hawkman]

I just purchased a set (7)wrenches markes S.C.U.S.A.I think they all are BSF. Does any one know what SCUSA stands for?There other numbers on the wrenches and they apear to be about fourty years old.

Bill - The tools should have markings on each end that show that they size is Whitworth or BSF (i.e. 1/4W or 1/4BSF). The other way to determine if they are Whitworth or BSF is to measure the space between the flats. If that space measures even 1/4, 5/16, etc., then they are AF (across the flats) or American sizes. I am sending you a chart of wrench AF measurements for American, British and Metric wrenches, that should be of some help to you in determining what you have. I have no idea what SCUSA stands for. By the way, Whitworth and BSF use the same AF measurements on the wrenches. The only difference is that a 1/4W wrench fits a 1/4W bolt head or a 5/16BSF bolt head, otherwise they are the same (albeit, somewhat confusing to the unitiated).
Cheers,

As per our phone conversation, i figured that the words originally read ACESA and not SCUSA but I was wrong!

I am contacting a few people that may know where these came from and who made them!!!

I thought that was being inturrupted by an Italian, as in
"Scusa me, is dat a Lancia or a Fiat?"

None of my contacts in the U.K. know what these letters mean so Tony's guess probably isnt far from the mark
