Mitutoyo 505-742 Dial Caliper 0 - 6", Graduation .001", .1"/rev
Part No. 505-742 | Range 0–6" | Graduation 0.001" | Accuracy ±0.001"
Product Overview
The Mitutoyo 505-742 is a mechanical Series 505 dial caliper with a 0–6" measuring range, 0.001" graduation and ±0.001" accuracy. It provides a practical battery-free solution for measuring outside dimensions, inside dimensions, depths and steps across a wide range of workshop and inspection applications.
The 505-742 incorporates the redesigned Series 505 dial movement, providing smooth slider operation and high shock protection for regular shop-floor use. Its analog dial provides a direct mechanical reading without batteries or electronic components.
This model has a 0.1" measuring range per revolution, with each dial graduation representing 0.001". The hardened stainless steel beam and standard hardened stainless steel jaws provide a general-purpose configuration for machining, fabrication, maintenance and incoming inspection.
Bezel and slider lock screws help retain the dial and jaw position when a measurement needs to be checked or transferred away from the workpiece. The caliper is supplied in a fitted plastic case for storage and protection.
For applications requiring a larger measuring range, the Mitutoyo 505-743 provides a 0–8" range with the same 0.001" graduation and standard jaw configuration.

Who This Product Is Best For
The Mitutoyo 505-742 is suited to machinists, quality inspectors, maintenance technicians, fabrication teams and workshop personnel who need a mechanical dial caliper for dimensions up to 6".
Its four measurement functions make it suitable for checking outside dimensions, inside dimensions, depths and steps with one instrument. The battery-free mechanical design is also useful for workshops where measuring tools are regularly exposed to coolant, oil and other shop-floor contaminants.
For applications where the measuring jaws may experience increased wear from abrasive materials, a carbide-jaw Series 505 model can be considered. The 505-738 and 505-736, for example, use carbide-tipped jaws in different configurations.
How to Use
-
Clean the measuring jaws and workpiece before measurement.
-
Close the jaws gently and check the dial zero. Adjust the bezel if required and secure the bezel lock.
-
Open the jaws beyond the dimension being measured and position them around, inside or against the feature.
-
Close the jaws gently using the slider until the measuring surfaces contact the workpiece without excessive force.
-
Read the beam and dial indication according to the 0.001" graduation.
-
Use the slider lock when the measurement needs to be retained while removing the caliper from the part.
-
Clean the instrument after use and store it in the supplied fitted case.
For critical inspection applications, verify the caliper against a suitable reference standard and follow the applicable calibration procedure.
