Hi Dick,
I must apologize for not being very clear about what PEM/screw I was referring to. Its good that you thought of the one you did as that is also important. The one I was referring to is labeled 2 (with a circle around the 2) on drawing E05-62. Its the screw that attaches the side(s) of the lid to the connector plate.
Sorry for the confusion, Chuck

Implicitly all that information existed already on the E05 60 Module drawing. I have today changed this drawing to Rev.02 to incorporate these specific dimensions. You have 28.4mm clearance to the cover flange of the E05 62 Connector Plate, which is intruded by 3.2mm for the cover screw and its PEM nut pressed into the flange. All other dimensions that you need are located on the several drawings, which is why I uploaded the complete set of drawings.

Hi Dick,
For those who have extreme connector issues it might be helpful if they had information regarding the cover attachment to the connector plate. This information might logically be added to the connector plate drawing.
How far does the nut protrude into the module area? What is it's diameter? What is the distance from the top of the PCB to the center of this nut (assuming 0.062 inch PCB)? And how far might the screw reasonably be expected to protrude into the module area?
Thanks,
Chuck

I have uploaded the drawings for the new E05 60, 140x180 Module, to
Eaglepedia. I did this so that people so interested can go there and
look at these drawings.
I plan shortly, however, to modify the PCB and Baseplate slightly by
adding more mounting screws. I have somehow to convey that some of the
added screws are optional depending upon the PCB dissipation. This
step to add more screws is part of the realization that screws spaced
50+mm apart may not provide sufficiently effective contact of the PCB
to the Baseplate. Modules such as the U Receiver will definitely need
the added screws. This tradeoff on this module is a significant
reduction in the need for added heat sinks, and their attaching screws
in the middle of the PCB.
Your timely comments on this module would be appreciated.
