Mitutoyo 505-742-52J Dial Caliper 6 Inch Inside Jaw

Product Description

The MITUTOYO 505-742-52J is a dial caliper designed for precise linear measurement in trade and industrial settings. It reads from 0 to 6 inches with a dial graduation of 0.001 inch and a stated accuracy of plus or minus 0.001 inch. The caliper body and jaws are stainless steel, providing corrosion resistance and long service life in shop environments. The inside jaw style makes it suitable for measuring internal dimensions such as bore diameters, slot widths, and pipe inner diameters. Machinists, pipefitters, HVAC technicians, and quality control personnel are the primary users.

This caliper is suited for residential and commercial shop applications where repeatable inside-dimension measurements are required. Typical uses include verifying bore sizes during pump or compressor service, checking pipe fittings for dimensional conformance, and quality verification of machined or fabricated components. The standard jaw adjustment type allows straightforward hand operation without special tooling. This tool is sold individually and is not sold in multi-piece sets.

Key Features

• Measurement range of 0 to 6 inches with 0.001 inch dial graduation
• Accuracy of plus or minus 0.001 inch for reliable precision readings
• Stainless steel construction for corrosion resistance and durability
• Inside jaw style for measuring internal dimensions and bore diameters
• Standard jaw adjustment for straightforward single-hand operation
• Not calibrated from factory — calibration should be performed per shop or site standards before critical use

Compatibility

Designed as a general-purpose inside-measurement dial caliper suitable for trade and industrial applications requiring 0 to 6 inch measurement range with 0.001 inch resolution.

Installation Notes

No installation is required for this hand tool. Before use, verify the caliper zeros correctly with jaws fully closed and confirm the dial reads zero at rest. If the tool will be used for quality-critical measurements, have it calibrated by a qualified metrologist prior to service. Store in the provided case when not in use to protect the rack, pinion, and dial mechanism from damage.
