I believe aerorocket is right about the graflex pins. The same question was asked here as well: http://forums.thecustomsabershop.com...lectrical-pins

As for the tool to install them, I found that a small piece of aluminum spacer (chassis disk spacer) works GREAT! Just stick the head of the pin in the little spacer tube, and use it to screw the badboy in, applying a moderate amount of pressure downwards. The aluminum is just soft enough to grip the hex heads well and screw them down snugly. Found that one out when my clumsy fingers had dropped the damn graflex pin while trying to finger tighten for the ninth time. Those things are TEENY!

Acerocket is correct (shocker?

) The G-Pins are indeed 3-48. I didn't have a small enough socket to use so I just used some fine-tip needle nose pliers to tighten mine down.

To drill and tap, you will need a #47 bit (.0785") and a 3-48 tap.

Anyone know the tap size to this?

Looks like the 5mm LED bezel from the store.

If it's that one, then it's listed on the first page:

For the 5mm LED bezel
- To tap and thread; M8x0.75 metric tap & 7.25mm Drill bit. 5/16-32 tap is not compatible with the Bezel

If it's something else, I don't know how to get you the thread information from just a picture.

I happen to have both the led bezel from Radio shack and the ones from the store, and the nuts are interchangeable, so i'd assume the threads size and pitch is identical, or close enough that they should both thread into the same size threads.
