Connection Studs
31
The main connection terminal studs are made from 1-1/8 -7 threaded material. All of the
mounting studs, and meter connection studs were drilled out to reduce material weight.
(3/4-10 threaded rod shown here)
Milling Nuts
32
As with the connection studs, the terminal and mounting nuts had to be light in weight.
This photo shows a piece of UHMW Polyethylene stock being milled into the required hex nut shape.

The UHMW stock was sliced creating individual hardware nuts which were then faced off
in a lathe on each side as shown here. The center hole is tap threaded to fit respective studs.
Turning Screws
35
There are three mounting screws visible on the back of the meter housing,
and two visible mounting screws securing the meter face inside the housing.
These items were also made from (plastic) to keep weight reduced.
Stud and Nut
36
Getting an idea of how the connection studs and nuts will appear with "copper"
color and "brass" color paint applied to simulated actual hardware fasteners.
