Outside Micrometers for Pipe, Tubing, and Flat Surfaces

Switch out anvils depending on the shape of the item you're measuring. Use the rounded anvil to measure the wall thickness of pipe, tubing, and other curved surfaces. Use the flat anvil to measure flat surfaces.
This micrometer has a friction thimble with a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening. Once the spindle stops tightening, the thimble will continue turning with resistance.
