Feeler Tape Gauge INSIZE 0.2 mm x 5 m (4621-20) precision gap measurement

Feeler Tape Gauge INSIZE 0.2 mm × 5 m (4621-20) is a narrow-width measuring tape designed for precise gap and clearance inspection. The slim 0.2 mm blade allows access into tight joints, seams and narrow crevices where standard tapes cannot reach. With a 5 m length it covers measurements across assemblies, components and long seams while preserving a compact handling profile for maintenance and quality control tasks.

Advantages

The thin 0.2 mm blade provides reliable contact in narrow gaps, enabling consistent measurements without deformation typical of wider tapes. The long 5 m reach reduces the need to reposition the tool when measuring extended parts or runs. Constructed for practical field use, the tape balances flexibility and stiffness to slide into crevices yet remain controllable during measurement. The simple, single-purpose design facilitates quick inspection cycles in workshop environments and on-site maintenance.

Suitable for

• Measuring gaps and clearances in mechanical assemblies and housings
• Inspection of seams and joints in sheet metal, piping and structural parts
• Maintenance checks where access is limited and narrow probing is required
• Quality control processes that require repeatable narrow-gap measurement

Key specifications

• Blade width: 0.2 mm for narrow-gap access
• Length: 5 m measuring range
• Narrow tape profile suitable for insertion into tight clearances
• Flexible but stable material to allow sliding into seams without buckling

How to use

Insert the slim tape blade carefully into the gap or seam until the required contact point is reached. Hold the tape steady and read the measurement at the reference edge or marking that aligns with the gap opening. For longer measurements, extend the tape along the seam while maintaining a straight line to avoid bending that could affect accuracy. Retract the tape slowly to prevent snatching or damage to the blade.

Usage recommendations

Use the feeler tape in clean, dry conditions and avoid dragging it across sharp burrs or rough edges to preserve the blade’s profile. Store the tape retracted and protected from strong bends or kinks. For repeated precision checks, verify measuring technique and reference points to maintain consistency.
