🚗 Wide Range of Applications
A variety of styles cover various fields to meet the needs of different professionals:

Automotive Maintenance: Engine valve clearance adjustment, spark plug gap measurement, brake pad wear inspection.

Instrument Testing: Checking clearances in precision mechanical components and gear meshing.

Manufacturing: Mold assembly and clearance measurement for machine tool calibration.

Factory Inspection: Production line quality control and equipment maintenance.

📖 How to Use
Cleaning: Wipe the feeler gauge clean with a clean cloth. Never take measurements if the gauge is contaminated with oil or grease.

Measurement: Insert the feeler gauge into the gap being measured. When you feel slight resistance, this indicates that the gap is close to the value marked on the gauge (which is the dimension of the gap).

Maintenance: After use, wipe the feeler gauge clean and apply rust-preventative oil to prevent rust, bending, deformation, or damage.

⚠️ Precautions
For your safety and to ensure the tool’s longevity, please be sure to follow these guidelines:

❌ Do not expose the tool to acidic or alkaline substances (to prevent corrosion).

❌ Do not force the tool into the gap during measurement (to prevent the gauge blades from bending or breaking).

❌ Keep the tool away from high-temperature environments during use.

✅ Keep the surface of the feeler gauge clean.
