UP-200 Screw MSBM2X5
These screws are typically used in securing outer housing parts (e.g., rear caps, front nose cover) or other structural sections of the handpiece where precise fasteners are required for high-speed rotation. For example, one listing states: “Outer Butt Cap Screws” in reference to MSBM2X5 for U-Power UG12 & SUG12 Handpieces.

Installation Tips
-
Confirm that your handpiece’s parts diagram or previous screw set lists MSBM2X5 specifically—some different revisions may use alternate screw sets.
-
Inspect the existing screw holes, threads and surrounding material to ensure there is no damage (e.g., stripped threads, deformed housing) that would affect fit.
-
Disconnect the handpiece from power and ensure it has fully stopped rotating.
-
Disassemble the relevant housing section (e.g., outer butt cap) where these screws are used.
-
Remove old screws, clean any debris or metal shavings from screw holes.
-
Install the new MSBM2X5 screws, ensuring correct driver head fit and that screws are seated flush with the head. Avoid over-tightening which can strip threads or deform housing material.
