Mitutoyo 505-743 Dial Caliper 0 - 8", Graduation .001", .1"/rev
Part No. 505-743 | Range 0–8" | Graduation 0.001" | Accuracy ±0.002"
Product Overview
The Mitutoyo 505-743 is a mechanical Series 505 dial caliper with a 0–8" measuring range, 0.001" graduation and ±0.002" accuracy. It provides a practical alternative to digital calipers when a battery-free measuring tool is preferred for everyday workshop use.
The redesigned Series 505 dial movement provides smooth slider operation and high shock protection for regular use in machining, fabrication, maintenance and inspection environments. The mechanical dial provides a direct analog reading without batteries or electronic components.
This model uses 0.1" of measuring range per dial revolution, while each dial graduation represents 0.001". The hardened stainless steel beam and standard hardened stainless steel jaws allow the caliper to measure outside dimensions, inside dimensions, depths and steps with one instrument.
Bezel and slider lock screws help secure the dial setting and sliding jaw when a reading needs to be retained or checked away from the workpiece. The caliper is supplied in a fitted plastic case for storage and protection between uses.
For a smaller measuring range, the Series 505 family also includes 0–6" models such as the 505-742J.

Who This Product Is Best For
The Mitutoyo 505-743 is suited to machinists, quality inspectors, maintenance technicians, fabrication teams and workshop personnel who need a mechanical dial caliper covering measurements up to 8".
It is particularly useful for general dimensional inspection where outside dimensions, inside dimensions, depths and steps may need to be checked with the same instrument. Its battery-free design can also be useful in workshop environments where measuring tools are frequently exposed to coolant, oil or other shop-floor contaminants.
For applications involving abrasive materials or frequent wear at the measuring surfaces, a carbide-jaw Series 505 model may be more appropriate. The 505-739, for example, uses carbide-tipped outside and inside jaws.
How to Use
-
Clean the measuring jaws and the workpiece before measurement. Close the jaws gently and check the dial zero.
-
If necessary, adjust the bezel so the pointer aligns with zero 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 part without excessive force.
-
Read the beam and dial indication according to the caliper's 0.001" graduation.
-
Use the slider lock when a measurement needs to be retained while the caliper is removed from the part.
-
Clean and store the caliper in its fitted case after use.
For critical inspection work, verify the caliper against an appropriate reference standard and follow your organization's calibration procedure.
Frequently Asked Questions
What can the Mitutoyo 505-743 measure?
The 505-743 measures outside dimensions, inside dimensions, depths and steps across its 0–8" measuring range.
What is the graduation of the Mitutoyo 505-743?
The dial graduation is 0.001". One complete dial revolution represents 0.1" of measuring range.
How accurate is the Mitutoyo 505-743?
The specified accuracy for the 505-743 is ±0.002".
Does the Mitutoyo 505-743 require batteries?
No. The 505-743 is a mechanical dial caliper and operates without batteries.
What type of jaws does the 505-743 have?
The 505-743 uses standard hardened stainless steel jaws. It is intended as a general-purpose configuration rather than a carbide-jaw version.
What is the difference between the 505-743 and 505-739?
Both models cover 0–8" and use 0.001" graduation with ±0.002" accuracy. The 505-743 has standard hardened stainless steel jaws, while the 505-739 has carbide-tipped outside and inside jaws.
What is the difference between the 505-743 and 505-743J?
The supplied catalogue information shows the 505-743J with the same 0–8" range, 0.001" graduation and ±0.002" accuracy. The exact distinction between the 505-743 and 505-743J should be confirmed against the specific stock or current Mitutoyo documentation before ordering.
Is the 505-743 suitable for general workshop measurement?
Yes. Its 0–8" range, mechanical dial, standard hardened stainless steel jaws and four measurement functions make it suitable for general dimensional measurement and inspection applications.
