Pin Gauge INSIZE 4110-4D00 metric individual pin gauge

INSIZE 4110-4D00 metric individual pin gauge is a single hardened and ground reference pin intended for precise measurement and inspection of hole diameters and fits. The pin gauge provides a defined diameter for go/no-go checks, calibration of measurement setups, and workshop quality control. It is made to deliver repeatable dimensional references in machining, toolmaking, and inspection tasks where accurate plug gauges are required.

Advantages

The solid, hardened construction ensures wear resistance and dimensional stability during repeated use. Ground finishing provides a true cylindrical form and accurate diameter tolerance, allowing consistent go/no-go assessments and fit verification. As an individual pin gauge, it is compact and easy to handle, facilitating quick checks on fixtures, jigs, and workpieces without the need for larger gauge sets.

Suitable for

• Verification of hole diameters and fits in machining and assembly
• Go/no-go checks during production and incoming inspection
• Calibration checks of measurement equipment and fixtures
• Use in toolrooms, inspection labs, and maintenance workshops

Key specifications

• Metric nominal diameter: individual metric pin gauge size (single pin)
• Material: hardened and ground steel for wear resistance
• Surface finish: precision ground cylindrical surface
• Tolerance class: manufactured to precision pin gauge tolerances for reliable reference measurements
• Form: straight cylindrical pin for accurate plug-in checking

How to use

Select the pin gauge size that corresponds to the target hole diameter or fit. Clean the pin and the hole or bore to remove chips, coolant, and debris before measurement. Gently insert the pin into the hole and check for proper fit: a smooth entry indicates acceptance while interference or excessive play signals out-of-tolerance conditions. Use the pin gauge for quick go/no-go checks, and in combination with other gauges or measurement tools for calibrated inspection procedures.

Usage recommendations

Store the pin gauge in a protective case or sleeve and keep it dry to prevent corrosion. Handle the pin by its shank to avoid touching the measuring surface. Periodically inspect and, if required, recalibrate or replace the pin if wear or damage affects measurement accuracy.
