Share with a friend:
The back side of the anvil stem of Fowler Ball-Anvil Tube Micrometers is cut away, making it slim enough to insert into small parts such as sleeves, collars, tubing and other cylindrical workpieces to measure wall thickness.
Measure dimensions from inside of holes to outside edges. The spherical anvil or spindle contacts the inside curved surface at a single point, permitting accurate gaging of wall thickness to .0001" or .001mm.
