[TheForge] Special Screw

[theforge@mailman.qth.net]

Sorry for posting something so far off topic.  I am getting desperate to find 
the type of screw and nut described below.

They were often used on tools such as "friction" type calipers, etc.  As I remember 
them the screw had a hex head that was very low in height and the hex was maybe 
7/16 or 1/2 in. or so.  They were like a shoulder screw in that they would hold the 
item together and would have a shoulder that was large but not very long.  Like for a 
caliper made from two pieces of .050 material the shoulder would only be about 
.100 long.  The threads would be a fine pitch (maybe 32 or 40 tpi) and the nut would 
have a low height.  They were used with a cup or bellville washer to keep the screw 
in tension..

I want to make some calipers with various motifs of the "girlie" design and would 
like  to use these types of screws to hold the two halves together.  In fact I think it's 
crucial to find an acceptable fastener or I'll forget the whole project.  No thanks, I 
don't want to make the screws and nuts.

If anyone knows where this type of screw and nut can be purchased, I would sure 
like to know. 

Thanks in advance for your help.
