SURFACE GAUGE USES

A surface gauge is very useful when finding the centre of a piece of round section material. It is normally used to ‘scribe’ parallel lines. Its base is heavy and this means it is stable when in used. Surface gauges sometimes have magnetic bases and this means they can be locked onto metal surfaces making it easier to use.
