A feeler gauge, also known as thickness gauge or gap gauge, is a precision measuring tool used in
metalworking to measure small gaps or distances between two metal surfaces. The gauge consists of a set of thin metal strips in various thicknesses, which is then packaged together in a tool designed to keep them organized.
In
metalworking, feeler gauges are primarily used to measure clearances between two machine parts. These clearances are crucial in ensuring optimal performance and longevity of the machine, as well as reducing the risk of damage or breakage due to improper fit. For example, feeler gauges can be used to measure the gap between the piston ring and cylinder wall in an engine, or the clearance between the valve and valve seat in a cylinder head.
One of the main advantages of using a feeler gauge is its high precision and accuracy. The thin metal strips used in the gauge are designed to be as close to the desired measurement as possible, ensuring that the measurement is as accurate as possible. This high level of precision is essential in ensuring that machine parts are properly fitted, reducing the risk of breakage and extending the lifespan of the machine.
Another advantage of using a feeler gauge is its versatility. The gauge can be used in a wide range of
metalworking applications, from measuring gaps and clearances in engines and other automotive parts, to measuring thicknesses and clearances in
metalworking and fabrication. This versatility makes feeler gauges a valuable tool for any metal fabricator or mechanic.
In conclusion, feeler gauges are an essential tool in
metalworking, providing a high level of precision and accuracy in measuring small gaps and clearances between machine parts. With their versatility, they are a valuable addition to any mechanic or fabricator's toolbox and can help ensure the longevity and optimal performance of machines and equipment.
