General Tech Services LLC — Genuine Mitutoyo Distributor, Kuwait +965 9807 4888
Product Overview
The Mitutoyo 513-404A is a horizontal-type metric dial test indicator (DTI) designed for precise comparative measurement where a conventional straight-plunger dial indicator cannot easily reach. Its pivoting lever contact can access bores, grooves, shoulders and other hard-to-reach features in machine shops and inspection environments.
It provides a 0.8 mm measuring range with 0.01 mm graduation and 8 μm accuracy. The balanced 0-40-0 dial allows deviations in either direction from the zero reference to be read clearly.
With a measuring force of 0.3 N or less, the 513-404A is suitable for delicate setup and inspection work. Its horizontal-type configuration is suited to centring, runout, concentricity and alignment checks, while the lever mechanism provides sensitive comparative measurement in industrial applications.
The Mitutoyo 513-404A is suitable for machinists, inspectors, toolmakers, maintenance teams, CNC setup technicians and machine shops across Kuwait.
For a more compact model intended for confined spaces, see the Mitutoyo 513-464-10E.

How to Use It
-
Mount the indicator securely in a suitable holder or magnetic base.
-
Position the lever contact against the surface or feature being inspected.
-
Keep the stylus as close to parallel with the measured surface as practical to minimise cosine error.
-
Apply a small amount of pre-load and rotate the bezel to set the reference position to zero.
-
Sweep the workpiece or rotate the spindle as required for the inspection.
-
Observe the movement of the pointer and read the deviation on either side of the zero position.
-
Avoid excessive contact force and maintain secure indicator mounting throughout the measurement.
Frequently Asked Questions
What is the Mitutoyo 513-404A used for?
It is used for precise comparative measurement such as centring, runout, concentricity and alignment checks, including measurements around bores, shoulders and other features that may be difficult to access with a straight-plunger gauge.
What are the range and graduation of the 513-404A?
The indicator has a 0.8 mm measuring range, 0.01 mm graduation, 8 μm accuracy and a balanced 0-40-0 dial.
What is the difference between a dial test indicator and a dial gauge?
A conventional dial gauge uses a straight-moving plunger, while a dial test indicator uses a pivoting lever contact. The lever mechanism allows a DTI to access features and surfaces that can be difficult to reach with a straight plunger.
What does the 0-40-0 dial mean?
The balanced 0-40-0 dial allows movement to be observed in both directions from the zero reference position, making deviations from a set reference easier to identify.
What is the measuring force of the Mitutoyo 513-404A?
The measuring force is 0.3 N or less.
How does the 513-404A compare with the Mitutoyo 513-464-10E?
Both are listed with a 0.8 mm range, 0.01 mm graduation, 8 μm accuracy and a 0-40-0 dial. The 513-464-10E is the compact model intended for confined measurement spaces, while the 513-404A is a horizontal-type DTI for general precision setup and inspection applications.
Can the contact point be replaced on the 513-404A?
Yes, a compatible replacement contact point can be used when required. The Mitutoyo 103006 is listed as compatible with the 513-404E, 513-464E, 513-444E, 513-454E and 513-284GE models. Confirm compatibility with the exact indicator model before ordering.
How should I mount the 513-404A for accurate measurement?
Secure the indicator in a suitable holder, position the lever contact correctly, minimise the stylus angle relative to the measured surface, apply the required pre-load and zero the bezel against the reference position before taking measurements.
