Length of Threads

Lee Dies of current manufacture (post Jan. 2002) have longer threads than previously manufactured dies. This was done for those who prefer to use Lee dies in other brands of presses that have thicker toolheads, turrets or castings. Unfortunately, Lee can not guarantee that the die will work with all brands of presses as far as length. The die bodies are standard 7/8 x 14 threads and will thread into any industry standard press.

Dies of older manufacture had threads which measured 1.75″ while current dies have threads of 1.85″. This measurement should be taken form the bottom of the die body to the top of the threads.

There is an exception pertaining to pistol bullet seating dies. Since this die is adjusted to sit further up than other dies, they have not been modified.
