Feeler Gauge INSIZE MWSB 0.02–1.0 mm L=100 mm (model 4602-17)

Feeler gauge INSIZE MWSB 0.02–1.0 mm L=100 mm (model 4602-17) is a precision measuring tool designed for assessing gaps and clearances with calibrated blades ranging from 0.02 mm to 1.0 mm. The tool features a compact overall length of 100 mm for convenient handling in workshops and during machine maintenance or assembly operations. Each blade is ground to provide consistent thickness across its length, enabling repeatable measurements of joint clearances and small component tolerances.

Advantages

The INSIZE feeler gauge provides accurate, repeatable gap measurement owing to precisely calibrated blades and consistent blade finish. Its compact 100 mm length allows access in confined spaces while maintaining user control. The set covers a broad range from 0.02 mm to 1.0 mm, making it suitable for fine adjustments and routine inspection tasks. Durable blade material and a secure fastening mechanism reduce the risk of blade deformation and ensure stable measurement conditions.

Suitable for

• Measuring valve and piston clearances in engines
• Checking bearing and shaft play during machine maintenance
• Setting spark plug gaps and small mechanical adjustments
• Assembly verification and quality control of tight tolerances
• Workshop inspection and calibration work requiring precise gap measurement

Key specifications

• Blade thickness range: 0.02 mm to 1.0 mm
• Overall length: 100 mm
• Material: hardened and ground measuring blades for stable thickness (material grade as specified by manufacturer)
• Blade finish: calibrated and ground for consistent measurement
• Design: multi-blade feeler gauge with individual blades secured by a fastening mechanism

How to use

Select the blade or combination of blades that approximate the gap to be measured. Insert the blade between the mating surfaces and slide gently; a proper fit will provide slight friction without forcing. If necessary, combine blades to achieve intermediate thicknesses until the correct clearance is identified. After measuring, clean blades and return them to the holder to protect the calibrated surfaces and maintain accuracy.

Usage recommendations

Store the feeler gauge in a dry environment and avoid exposing blades to corrosive substances. Clean blades before and after use to preserve calibration. Use gentle pressure when measuring to prevent blade bending; if precise traceability is required, verify gauge accuracy periodically against a certified reference.
