Tape Feeler Gauge INSIZE 4621-02 — 0.02 mm Graduation, 5 m Length

Tape feeler gauge INSIZE 4621-02 is a flexible gap-measuring tool with a 0.02 mm graduation and a 5 m tape length. It is designed to measure narrow gaps, clearances and joint widths in machinery, sheet metal and assembly work. The fine scale provides repeatable readings for setup, inspection and maintenance tasks where high resolution is required.

Advantages

The tape feeler gauge combines a long, flexible steel tape with a finely graduated scale to enable precise measurement of small clearances over extended distances. Its 0.02 mm graduation delivers higher resolution than common 0.1 mm tapes, improving the accuracy of gap and joint width assessment. The compact, retractable design protects the tape during transport and storage while allowing quick extension and retraction during use. The clear, etched graduations remain readable under typical workshop conditions, supporting consistent measurements for repeated checks and setups.

Suitable for

• Measuring narrow gaps and clearances on machinery and engines
• Checking joint widths and seam gaps in sheet metal and fabrication work
• Inspection and setup tasks in maintenance and assembly operations
• Situations requiring fine resolution measurement over several metres

Key specifications

• Graduation: 0.02 mm
• Tape length: 5 m
• Tape type: flexible steel tape with etched scale
• Scale readability: fine, high-resolution graduations suitable for precise gap measurement
• Housing: compact, retractable design for tape protection and portability

How to use

Extend the tape from the housing and align the graduated scale across the gap or clearance to be measured. Hold the tape straight and flat against the contact surfaces to minimise bending or sagging that could affect accuracy. Read the nearest graduation marking at the point of contact and, when required, take multiple measurements along the joint to assess uniformity. Retract the tape slowly into the housing after use to avoid kinking or damage to the etched scale.

Usage recommendations

For best results, ensure measuring surfaces are clean and free of debris before taking readings. Avoid excessive bending beyond the tape's natural flex to maintain graduation accuracy. Store the tool in a dry environment and wipe the tape after use to prevent corrosion and preserve legibility of the graduations.
