THREAD LOCKER

The Thread locker is a specific adhesive applied to the Threading of a screw to prevent it from loosening unexpectedly due to vibrations or shocks. Its adhesion is deliberately moderate: it holds the screw in place during use, while still allowing it to be unscrewed normally with a Screwdriver, without damaging it. In watchmaking, the Brake–Thread is mainly used on External parts (case, dial, hands) components — Bezel screws, Case back, of Bracelet / Strap or of Crown — subject to handling and vibrations, where loosening would lead to loss of a part or ingress. It comes in various strengths, from the weakest (removable by hand) to the strongest. Its use must remain measured and clean, as an excess can migrate to sensitive areas or complicate future disassembly. A simple Assembly product, the Thread locker contributes to the reliability and safety of watches, ensuring that screwed connections hold over Time.
