Series 12 centesimal micrometers with vernier 0-300 mm

Painted frame with hard metal contacts. Easy reading thanks to careful character execution and incision depth. Particularly accurate spindle screw machining, obtained in an environment kept at 20°C. The screw is fully hardened and stabilized; after roughing the thread, it is subjected to a special ageing treatment before finishing, to prevent variations due to residual internal stresses. Contact surfaces are extremely finely finished Ra 0,025 µm.

Locking device easily accessible. Thermal insulation plates applied to the frame. Steel lamina friction which, depending on size and position on the drum, meets the dual requirement of accessibility both on the support (see item SUM) and in the more frequent use with the workpiece and tool held in hand. They feature a counter reading system that makes them extremely easy to use, even for non-expert personnel. Frame with thermal insulation. Hard metal contacts.
