With a deluxe tumbler. This model uses the larger 8-32 thread hammer screw. (If you built your small Siler lock from a kit, it will not be a Deluxe. It will have the smaller 6-40 thread hammer screw and the standard tumbler.) Use a full size 3/4" X 7/8" flint, #FLINT6FR. Plate measures 4 3/4" X 7/8".
