Introduction — The silver-finish screwed-rivet T-bar is a fixing system used on many Cartier watch straps and on certain Hermès and jewellery references. It comprises a transverse bar and a screwed peg providing invisible, symmetrical attachment.
Product overview
The set is machined from stainless steel with a thin silver-finish coating. The rivet screw is tightened with a 1.2 mm flat screwdriver. The bar features two side notches that hold it from rotating during tightening. The system is appreciated for its strength far above that of a regular spring bar: no spring to fatigue, the strap is mechanically locked.

How to use
- Locate the two side screws of the strap at the base of the lugs.
- Unscrew with a 1.2 mm flat screwdriver under steady pressure.
- Pull the broken bar with fine pliers.
- Insert the new T-bar aligning the notches.
- Tighten the rivets crosswise without forcing; check strap squareness.

FAQ
Does it fit every Cartier?
Classic rivet-strap models (Tank, Santos, Pasha, Roadster). For recent proprietary attachment models, check dimensions before buying.
Which rivet length should I choose?
Length depends on model. For a Tank Solo, 1.5 mm fits; for a Santos XL, 1.8 mm is needed (separate reference).
Is the screwdriver included?
No. A 1.2 mm flat screwdriver is required; it is available separately in our catalogue.
