Moore & Wright Caliper - 150mm (6in)

The caliper is manufactured from polished tool steel, with the marking leg point hardened to over 550Hv.

The bow spring ensures uniform tension over the working range, providing consistent pressure and performance.

The centrally mounted adjustment screw allows for fine and precise setting of the caliper's jaws, offering more control than firm-jointed types.

Yes, as a hermaphrodite caliper, it is designed to take both internal and external measurements, as well as marking parallel lines.

This model is 150mm (6 inches) in size.

Store the caliper in a dry place, preferably in its original packaging or a protective case, to prevent corrosion and damage to the polished surface.

While precise for its type, it is designed for layout and general measurement tasks. For measurements requiring the highest level of precision (e.g., to within microns), tools like micrometers are recommended.

Clean any debris from the screw threads. Apply a small amount of light machine oil to the threads and pivot point, then work the screw back and forth to distribute the lubricant.

The hardened point can be sharpened on a fine grinding stone or hone if necessary. Exercise caution to maintain the original profile.

Check for any dirt or obstructions around the pivot and bow spring. Clean the area and apply light lubrication.

Ensure the caliper is being used on a flat surface and that the adjustment is made correctly. Re-check measurements against a known standard if available.
