Hi Eddy, The only reference to 48 gage I have access to is Machinery's Handbook (26th edition). They list 48 gage as 0.00152" based on the old (established 1914) Birmingham Gage. Hope this helps. RedPen

Gages this small are generally wire gages. The gage system used by practically all steel producers in the US is the Steel Wire Gage. This gage name has the official sanction of the Bureau of Standards at Washington. Although the Birimingham Gage has been reconized by Acts of Congress it is all but obsolete in the US and Great Britain, where it originated. This stated because the Manufacturer's Standard Gage for Sheet charts I have found do not extend into the shim gage sizes. The Steel Wire Gage decimal equivilant of #48 is .0048". Interesting that the size comes out to the same numerals, this is just an accident. However, RedPen is correct about the Birimingham gage for sheet metal. As per my experience, I find that most metals of this thin a cross section are rated as shim stock and called by their thickness in thousands of an inch. IE: .005 brass shim stock, or .003 stainless steel shim stock, or.001 blue steel shim. As time continues thickness in thousands per inch are slowly replacing the gage systems. Reason being there has been and continues to be confusement as to which gage system to use or of which gage system has been specified. I would recommend that you either specify a thickness or request a clarification as to which gage system to reference, or request a specification (with tolerance) in thousands of an inch by your customer or vendor. -randy- The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
