While both are made in stainless and blued, there are only two different front side plate or yoke screws. About 1990 S&W added a spring loaded hardened pin in the end of yoke screws. The newer style are obvious because their head diameter is larger than the other two side plate screws.
Since Model 10s are blued or nickel plated their screws would look wrong in a stainless Model 64.

The new yoke retention system, which included a redesign of the yoke stem and a new yoke screw with a spring loaded plunger was first used in the model 64 in 1988. (authority the Catalog, 3rd Ed.)
The revision number for the model 64 which incorporate this change was the dash 4 (2 inch bbl), and dash 5 (3" and 4" heavy bbl versions).
Although they will be the wrong color (blued), Model 10 yoke screws that are the re-designed version with the plunger and spring will work in the model 64's marked as -4/-5 and later.
Yoke screws used prior to the re-design held the yoke in place using a pilot on the end of the screw stem, which, when fully assembled in the sideplate, entered a slot at the end of the yoke stem, and bore on the "button" at the end of the stem. This interface between the button on the yoke and the screw on these early models was hand fit during assembly.
