Feeler gauge set. A feeler gauge is a tool used to measure gap widths. Feeler gauges are mostly used in engineering to measure the clearance between two parts. They consist of a number of small lengths of steel of different thicknesses with measurements marked on each piece.
There are two main types of gauges on the market: liquid-filled gauges and dry gauges. A liquid-filled gauge is tougher and more durable than a dry gauge. If a dry gauge is under extended shock and vibration, its internals can get damaged and the needle falls off.
