Can someone tell me the depth of the body where the mounting screw goes? I'm trying to determine how long a screw I need to mount to the cartridge carrier on my Empire 980 arm. The carrier uses a special nut that nestles into the slots, and then screws that came with it are short. The cartridge is on its way and I want to try to source the screws quickly. Thanks!
Only these special nuts fit the carrier?
According to the link the slots on the cart are 8.5mm. That's the distance from the screw head (on the bottom) to the top of cart.
Determine the distance from the top of the cart to the nut - the thickness of nut/cart platform.
Most nuts are 2mm deep. Chances are a 10mm screw will do it. Even if it's not exactly at the end of the nut it will probably hold it. It depends on how far away the nut is from the top of the cart.
Screws come in 10 and 12mm or 1/2" is about 12mm. If you have to go over, get the smallest metal washers that will fit the screw and use them under the screw head.
The only other problem is size. These screws might be hard to source locally. 2.5mm is kind of a standard now,
but what are those old nuts? [sounds like a bad song] I suspect another close size will fit?

Just a note about screw size: This is the diameter of the screw thread. It might be 3-48 size like in the first link. I think other size hex nuts might fit the carrier. Screws and bolts also come in different threads (the 48 part) and hopefully "standard" thread won't be a problem.
If you need to use washers between screw head and cart, metal washers might be a little wide and push the screw out sideways. Nylon washers are thinner diameter and need to be compressed to make a secure mount. If you can remove the carrier from the headshell, you can get long screws and after you mount the cart in the carrier, cut off the ends to fit under the headshell.
