INSIZE gap tape gauge 0.4 mm x 5 m 4621-40 — measuring tape for gap/clearance measurement

INSIZE gap tape gauge 0.4 mm x 5 m (4621-40) is a flexible measuring tape designed to check gaps, clearances and joint alignments in mechanical, installation and construction tasks. The tape combines a uniform 0.4 mm thickness profile with a 5 m length, allowing measurements of narrow gaps over extended distances and repeated checks during assembly, setup or maintenance.

Advantages

The flexible construction conforms to curved and uneven surfaces while preserving the 0.4 mm thickness needed for accurate clearance assessment. Its 5 m length enables long-reach measurements without repositioning, and the material resists common workshop wear to provide consistent results during repeated use. The gauge is compact and easy to handle, making it practical for on-site verification and routine maintenance checks.

Suitable for

• Checking clearances between mating parts in mechanical assemblies
• Verifying joint and seam gaps in construction and installation
• Alignment and setup tasks where narrow gap measurement is required
• Routine maintenance inspections and quality control checks

Key specifications

• Thickness: 0.4 mm
• Length: 5 m
• Flexible tape suitable for curved and flat surfaces
• Designed for gap and clearance measurement

How to use

Place the tape into the gap or along the seam to be measured, ensuring the tape sits flat and fully engages the surfaces being checked. For long runs, extend the tape along the joint and read the point where the gap is constrained by the tape thickness. Use multiple positions to confirm uniform clearance across a surface. Store the tape flat or rolled without tight creasing to maintain its thickness profile.

Usage recommendations

Use the gauge at room temperature and avoid exposure to solvents or extreme heat to preserve dimensional stability. For repeatable results, clean contacting surfaces before measurement and inspect the tape regularly for nicks or permanent deformations that could affect accuracy.
