Ratchet screws

Ratchet screws are specially manufactured screws that are used in the barrel and winding mechanism of mechanical watch movements. They secure the ratchet wheel to the barrel arbor or ratchet bridge and ensure that the force of the mainspring is transmitted and maintained in a controlled manner. Their quality is crucial to the reliability of the entire winding mechanism.

• Fastening the ratchet wheel to the barrel arbor or ratchet bridge
• Securing the power transmission between the mainspring and the gear train
• Stabilizing the winding mechanism, especially when winding the spring
• Preventing play or twisting under high loads

Ratchet screws must withstand high torques, as they are directly loaded when the watch is wound.
