The Major LS-12-25PK is listed as a set xxxx for mortise lock replacement, and the available size spec shows it as an 8-32 x 1/2" hex set xxxx . That means the thread size is #8-32 with a 1/2" length.
For diameter, a #8 machine xxxx has a nominal outside thread diameter of about 0.164" (roughly 5/32"). So if you are matching an existing xxxx , the key dimensions are #8-32 thread, 0.164" diameter, and 1/2" length.
