Mitutoyo 505-743J | Dial Caliper | Series 505 | Type Silver Cover | Graduation 0.001 Inch | Acuracy ±0.002 Inch | Range 0 to 8 Inch | Weight 185 g
Part No. 505-743J | Range 0–8" | Graduation 0.001" | Accuracy ±0.002"
Product Overview
The Mitutoyo 505-743J is a Series 505 mechanical dial caliper designed for measuring outside, inside, depth and step dimensions across a 0–8" range. It provides ±0.002" accuracy with 0.001" graduation and operates without batteries, making it suitable for routine dimensional inspection in machining, fabrication, maintenance and quality-control environments.
The 505-743J uses Mitutoyo's redesigned Series 505 dial movement for smooth slider operation and high shock protection. Its hardened stainless steel construction is suited to regular shop-floor use, while the analog dial provides a direct mechanical reading.
The dial has a 0.1" range per revolution, with each division representing 0.001". This configuration provides a clear mechanical indication while avoiding the need for a digital display or battery. A bezel lock screw secures the dial setting, while the slider lock screw can hold the jaw position when a measurement needs to be retained.
This version uses standard hardened stainless steel jaws for general-purpose dimensional measurement. The jaw configuration makes it suitable for a wide variety of workpieces where carbide-tipped measuring faces are not specifically required.
For a smaller measuring range, the Mitutoyo 505-742 covers 0–6".

Who This Product Is Best For
The Mitutoyo 505-743J is suitable for machinists, quality inspectors, maintenance technicians, fabrication workshops and dimensional inspection teams measuring components up to 8".
Its standard hardened stainless steel jaws make it a practical configuration for general-purpose measurement across a variety of materials and workshop applications. The battery-free mechanical design is also useful where a straightforward analog measuring instrument is preferred.
With outside, inside, depth and step measurement capability, the 505-743J can handle multiple routine inspection tasks without requiring a separate tool for each measurement type.
How to Use the Mitutoyo 505-743J
-
Clean the measuring jaws and workpiece before measurement.
-
Close the jaws gently and check the dial position. Adjust the bezel to zero when required and secure it with the bezel lock screw.
-
Open the jaws beyond the feature being measured.
-
Position the appropriate measuring jaws squarely against the workpiece.
-
Close the jaws gently using the slider/thumb roller until proper contact is established.
-
Read the beam scale together with the dial indication to determine the measurement.
-
Use the slider lock screw when the jaw position needs to be retained for inspection or recording.
-
Clean the caliper after use and return it to its fitted plastic case.
For repeatable measurements, keep the measuring surfaces clean, avoid excessive measuring force and maintain proper alignment between the caliper and workpiece.
