Thickness Feeler Strip
Description
A Thickness Feeler Strip, commonly known as a Feeler Gauge, is a precision measuring tool used to measure small gaps or clearances between two surfaces. It consists of a set of thin metal strips of known thickness.
Uses
- Measuring small gaps and clearances
- Checking valve clearances in engines
- Used in machine setup and maintenance
- Inspection and alignment work
Parts
- Set of thin metal strips (leaves)
- Pivot screw or holder
- Thickness markings on each strip
Material
- Hardened and tempered steel
- Stainless steel (in some types)
Working Principle
The Thickness Feeler Strip works on the principle of gap comparison. A strip of suitable thickness is inserted between two surfaces. If it fits snugly without force, the gap size matches the thickness of the strip.
Advantages
- Simple and easy to use
- Provides accurate measurement of small gaps
- Portable and compact
- Available in multiple thickness sizes
Safety Precautions
- Handle strips carefully to avoid bending
- Keep clean and free from oil and dirt
- Avoid forcing the strip into tight gaps
- Store properly after use
Conclusion
The Thickness Feeler Strip is an essential measuring instrument for checking clearances and gaps with high accuracy. It is widely used in mechanical and maintenance work for precision inspection.
