Mitutoyo Dial Caliper 505-742-51 Ultra Smooth Sliding Shock Protection

Description

Product Overview

The Mitutoyo 505-742-51 dial caliper is engineered for professionals who demand precision, durability, and ease of use in demanding measurement tasks. Built with a high‑grade stainless steel body, the instrument resists corrosion and maintains its calibrated accuracy over years of heavy use. The new dial movement design delivers ultra‑smooth sliding, reducing friction and providing a tactile feel that helps users lock in measurements quickly and confidently.

One of the standout innovations is the removal of the traditional tin coating on the sliding surfaces. This change eliminates a common source of wear while preserving the long‑term durability of the measurement jaws. The result is a caliper that retains its accuracy even after thousands of measurement cycles, making it ideal for production environments where consistency is critical.

Additional features include a lock screw that secures both the dial bezel and the sliding jaw position, preventing accidental movement during transport or while taking multiple readings. The caliper can measure outer diameter (OD), inner diameter (ID), depth, and step dimensions, covering a broad range of applications from mechanical engineering to quality control in manufacturing.

With a compact size of 10.6 x 4.5 x 1.4 inches and a lightweight design of just 12 ounces, the tool is comfortable to handle for extended periods. The clear, easy‑read dial face displays measurements in both metric and imperial units, allowing users to switch seamlessly between systems without the need for additional conversion tools.

Manufactured by Mitutoyo, a globally recognized leader in precision measurement equipment, this dial caliper meets the rigorous standards of the industrial and scientific markets. Its best‑seller rank in the Dial Calipers category reflects the confidence professionals place in its performance and reliability.

Usage

Designed for a wide variety of environments, the Mitutoyo 505-742-51 excels in both shop‑floor and laboratory settings. In manufacturing plants, technicians use the caliper to verify the dimensions of machined parts, ensuring that each component meets tight tolerances before assembly. Its shock‑protected design tolerates the occasional bump or drop that can occur in busy workshop floors, reducing the risk of damage and costly recalibration.

In research and development labs, engineers rely on the caliper’s precise measurement capabilities to evaluate prototype parts, compare design iterations, and document dimensional changes over time. The ability to measure both OD and ID without changing tools streamlines the workflow, saving valuable time during testing cycles.

Field service professionals also benefit from the tool’s portability and rugged construction. Whether inspecting equipment on a production line, performing maintenance on heavy machinery, or conducting on‑site quality checks, the caliper provides reliable data that supports decision‑making and compliance with industry standards.

FAQ

What measurement ranges does the caliper cover?

The Mitutoyo 505-742-51 dial caliper measures outer diameter, inner diameter, depth, and step dimensions up to 6 inches (150 mm) with a resolution of 0.001 in (0.02 mm). This range accommodates most standard industrial parts and components.

How do I maintain the caliper for optimal performance?

Regular cleaning with a soft, lint‑free cloth and mild solvent removes debris and prevents corrosion. Periodic calibration, preferably annually or after any impact, ensures the dial remains accurate. Store the instrument in its protective case when not in use.

Can the caliper be used with both metric and imperial units?

Yes. The dial face includes dual‑scale markings, allowing users to read measurements in either metric (millimeters) or imperial (inches) units. Simply align the zero marker with the appropriate scale for the desired unit system.

Is the lock screw adjustable for different jaw positions?

The lock screw is designed to secure the current jaw position, preventing accidental movement. While it does not provide continuous adjustment, it can be loosened to reposition the jaws when switching between measurement types, then tightened again for stability.

What warranty does Mitutoyo provide?

Mitutoyo offers a standard one‑year limited warranty covering manufacturing defects. Extended warranty options are available through authorized distributors, providing additional peace of mind for high‑volume users.
