This thread is for noting the common dimensions of flashlight parts. This should help when a modder is helping someone with a light that they have not seen. It would also help when determining if the appropriate taps, dies and other materials are on hand before starting a project.

This thread should be listed in the "threads of interest" thread.

Measurements of interest are;

Threads; pitch, number of threads, major and minor diameters

Battery sizes; Designed and measured.

Flashlight tubes; length, bore, wall thickness.

And, of course any others.

Please post only the measurements in this thread. This is for reference material. Discussion can happen in other threads

I suggest the mesaurements for only one light per post.

The head is a poor conductor. The ground path is through the top edge of the battery tube to the silver washer that sits on the shelf.

The electronics are pressed into a recess at the head end of teh battery tube.

Maglight D cell body;

20 tpi, both ends.


Measuring the body at the head....


1.533 inches major (maximum reading on outside of threads)
1.511 inches minor (minimum reading at root of threads)


Measuring at the tailcap...
1.430 Tailcap major (outside of tailcap threads.
1.385 Body minor (inside threads)


In addition, the body on the tail end has a .185 deep smooth area at the very end for the O-ring to seat against. The diameter there is 1.440. The threads themselves are only about 1/2 inch, if that. The area beyond the threads is recessed, probably to is 1.440.
