This M54 fine-adjustment set contains three thin aluminium spacer rings: 0.3 mm in black, 0.5 mm in red and 1 mm in gold. The rings fit between the shoulders of compatible M54 threaded parts.
A ring slightly increases the separation at a threaded joint and changes the final rotational orientation as the joint is tightened. The thin spacer also helps prevent two threaded components from binding together.
These are unthreaded shims, not short extension tubes with male and female threads. Select the thickness to achieve the required spacing while retaining adequate thread engagement.
Baader manufacturer documentation
Exact three-ring set matched. Rings are unthreaded according to manufacturer description; catalogue connection-family tags are not interpreted as threads cut into the rings. M54 parent text contains an inconsistent reference to M48 diameter, so no unsupported physical inner/outer diameter is assigned to the M54 set.
