Feeler Gauge INSIZE 0.05–1.00 mm Range Length 200 mm

Feeler Gauge INSIZE 0.05–1.00 mm Range Length 200 mm is a precision hand tool intended for gap and clearance measurement between mechanical parts. The gauge includes a set of thin blades calibrated across the 0.05–1.00 mm range and mounted on a 200 mm backing, allowing access to narrow joints and providing tactile feedback for setting clearances, adjusting components and checking tolerances in workshop and maintenance environments.

Advantages

The feeler gauge offers a wide incremental range from 0.05 to 1.00 mm with fine steps for accurate thickness selection and repeatable measurements. Its 200 mm overall length improves reach into assemblies while maintaining blade stability during use. Constructed from tempered, ground blades, the tool provides consistent thickness across its set and resists wear in typical workshop conditions. The simple folding design protects unused blades and makes the gauge compact for storage.

Suitable for

• Measuring gaps and clearances between mating parts
• Setting and adjusting valve, bearing and shim clearances
• Inspection of mechanical tolerances during maintenance
• Workshop setup tasks and precision assembly checks

Key specifications

• Measurement range: 0.05–1.00 mm
• Overall length: 200 mm
• Material: tempered and ground steel blades
• Design: folding blade assembly for compact storage
• Application: manual gap and clearance measurement

How to use

Select the blade or combination of blades that approximates the expected gap thickness and fold them out from the backing. Insert the blade tangentially into the gap and slide gently until a light friction is felt; adjust by trying thinner or thicker blades to achieve the desired fit. When the correct thickness is found, record the value and retract the blades. After use, fold blades back to protect edges and store the tool in a dry place.

Usage recommendations

Keep blades clean and free of oil or debris to preserve measurement accuracy. Do not force blades into undersized gaps to avoid blade deformation. For repeatable results, perform measurements at consistent temperature and avoid prolonged exposure to corrosive environments.
