Starrett 196B1 Back Plunger Dial Indicator 0-20-0 Range

The Starrett 196B1 Back Plunger Dial Indicator delivers 0 to 0.200 inches of travel on a 1-1/2 inch dial, with 0.001 inch graduations and a 0–100 reading scale, enabling precise, easily readable measurements in inspection and setup tasks, and it is part of Starrett's universal back-plunger indicators family. Designed with the contact point on the back, readings can be read from above even in cramped fixtures; it uses a 1/4 inch shank diameter to fit standard stands and adapters, with a typical range-per-revolution around 0.1 inch, making it straightforward to map small deflections to the dial. Common applications include bore and fixture inspection, alignment verification, runout checks on rotating parts, and other metrology tasks in mechanical shops and QC environments where consistent 0.001 inch resolution and repeatable readings are essential.
