Gap Tape Feeler INSIZE 4621-03, 0.03 mm Thickness, 5 m Length

INSIZE Gap Tape Feeler 4621-03 is a thin, uniform measuring strip designed for accurate gap and clearance measurement. With a thickness of 0.03 mm and a length of 5 m, this gap tape feeler is intended for inspection and setting of small clearances in mechanical assemblies, sheet metal work and bodywork, and routine maintenance tasks. The consistent thickness across the tape allows repeated checks and helps achieve uniform results during adjustment and inspection operations.

Advantages

The 0.03 mm thickness provides precise, repeatable contact for fine clearance checks. The 5 m roll length gives enough material for multiple measurements and extended use without frequent replacement. The tape's uniform cross-section and flexibility make it suitable for reaching narrow gaps and conforming to curved surfaces while maintaining measurement consistency.

Suitable for

• Measuring and setting small clearances in mechanical assemblies
• Sheet metal and bodywork gap inspection
• Routine maintenance and adjustment tasks requiring thin feeler material
• Quality control where repeated, consistent thickness checks are needed

Key specifications

• Material: precision-ground measuring strip (uniform thickness)
• Thickness: 0.03 mm
• Length: 5 m
• Form: tape/roll suitable for cutting to required length
• Flexibility: suitable for flat and slightly curved surfaces

How to use

Cut or unwind a suitable length of the gap tape feeler and insert it into the gap or clearance to be measured. Slide the tape gently to determine whether the tape passes through the gap with the expected resistance; if it fits snugly, the gap corresponds to the tape thickness of 0.03 mm. For setting clearances, use the tape as a spacer during adjustment, then remove or leave a cut section in place as required by the application. Store the remaining roll flat or in a protective sleeve to avoid creasing and maintain uniform thickness.

Usage recommendations

Use clean, dry surfaces and avoid excessive bending or folding of the tape to preserve its uniform thickness. For high-precision checks, ensure mating surfaces are free of debris and oil. Replace the tape if it shows visible wear, permanent deformation, or contamination that could affect measurement accuracy.
