[GreenKeys] Screw Sources

[Don Robert House]

Robert,

I have pounds of Teletype hardware here but finding exact parts takes  
a very long time.

Many types of screws and associated fasteners are available at

www.boltdepot.com

Their service is efficient and fast.

No, cap screws start at 1/4"  Machine screws stop at #14.  But #14 is  
rare
and #12 uncommon.

There are (or were) 3/16" and 1/8" stove bolts.  I forget exactly what  
the
1/8" was but a 3/16" stove bolt is substantially the same thing as a  
round
head slotted #10-24 machine screw.

One thing I remember about working on Model 15's is that the majority  
of of
#6 and #8 machine screws are #6-40 and #8-36.  You don't often run into
either of those much of anywhere else.
