Range: 0-1" | Resolution: 0.0001" | Part Number: 52-240-001-1Fowler 52-240 series Vernier-scale micrometers have a choice of measuring range and a 0.256" diameter flat anvil/spindle pair for general purpose measuring. The Vernier scale has 0.0001" graduation intervals and 0.0001" accuracy for precise and accurate readings. The anvil/spindle pair have hardened, precision-ground, and micro-lapped measuring faces with 0.00003" flatness. The positive locking lever on the spindle locks measurements in place for accurate readings and the zero adjustment on the sleeve ensures accurate measurements. Friction thimble with ratchet stop applies constant force for repeatability between users. Friction-style thimbles are suitable for one-handed operation and stop turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. The ratchet-stop thimble can be used independently of the friction thimble. It provides an audible sound and stops the spindle from turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators.
