This invention relates to stamped sheet metal
vnuts of ‘the type forming the subject matter of
myrrpending application for patent, Serial No.
553,640, ?led September 11, 1944, which has be
come Patent No. 2,379,892, patented July 10, 1945.
It has been the practice as exempli?ed in my
application above identi?ed to strike out from
a sheet metal body portion a pair of laterally
juxtaposed generally rectangular bridge portions

with S‘LlCh‘QthB!‘ objects and advantages as may

each bridge portion where the edges l5 are lo
cated is approximately that of its anchored end
portions. In other words, for a given adequate
mid-width of the bridge portions the anchored
ends need be no wider than such given width
and could be of lesser width, whereas if the
