A feeler gauge is a tool made up of various metal blades used to measure small gaps or clearances between two objects, and it's commonly used in engine maintenance for precise measurements.
Explanation:
A set of calibrated metal plates used to measure clearance or gap is referred to as a feeler gauge. A feeler gauge is a tool consisting of a series of metal blades or wires of varying thicknesses, which are used to measure the size of small gaps between two objects. When using a feeler gauge, the blade that fits snugly without excessive force indicates the gap size. This tool is often used in a variety of applications such as engine work, where precise measurements are crucial for the performance and safety of the machinery.
