Comparison Cogwheels Z10 And Z13 For Gear Locks

For cylinder locks with cogwheel cams, Z10 and Z13 refer to the number/type of teeth on the gear, not the cylinder length. Z10 — 10 teeth, typically about 24 mm diameter. Z13 — 13 teeth, typically about 30 mm diameter. They are used instead of a standard DIN cam to drive certain multipoint/mortise locking mechanisms. They are not interchangeable just because the cylinder fits the door; the cogwheel has to match the gearbox/lock mechanism.
