Rupert,

Utilizing the most stringent scientific testing, I have determined that the Viel tracking screws have a 10 x 24 thread 3/8" long. (I removed one screw and threaded it into the threaded hole in my electrician's multipurpose pliers used to cut off screws. The 10-24 hole threaded perfectly.)

From the local hardware store:

2 each Plastic knobs with threaded stud 10x24 x1/2"

2 each Brass nuts 10-24 their height will be 1/8" that gets us to the threaded length of 3/8 inch required for the spring to work AOK
