Starrett 1150Z-2 dial indicator snap gage with 0-2" measuring range and .0001" graduations. Shockless mechanism and continuous dial with +10/-10 .040" reading for precision comparative measurements in inspection and quality control applications.

These compact gages have rigid aluminum alloy frames protected from hand heat by insulating handles. They are used to gage outside diameters to an accuracy of .0001". Dimensional variations are transmitted to the dial indicator through a linear friction-free transfer mechanism totally enclosed for protection against side thrust, foreign matter and coolants. Flat gaging contacts simplify measurement close to shoulders. The top sensitive contact may be reversed to present a spherical face to the work. An adjustable backstop simplifies centering the work. 0-2" Range, in Case.

Features

• The contacts and backstop are 5/16 in diameter hardened tool steel, precision ground and lapped flat
• Contacts are individually adjustable to maximum 2 in range and are locked in position by tightening parallellock clamps to maintain parallelism of faces
• Both contacts are also keyed to maintain orientation of faces regardless of adjustment
• Plus and minus are read directly
• Dial face has a double row of graduations reading in opposite directions, red "Minus" and black "plus" grads
• The indicator can be rotated 360 deg and locked in position to read from any angle and a fine-adjusting screw provides for zero setting the hand
• A guard protects the dial indicator when the gage is laid down
• 0.3125 in anvil diameter
