Feeler gauges are precision tools that measure gap widths in many types of material. Commonly used for engineering applications, a feeler gauge is predominantly used to measure the clearance between two parts. The individual feelers are called leaves or blades, and come in tapered and parallel styles. A feeler gauge set contains more than one blade, typically in sets of 15 to 36. Another type of gauge tool, a shim stock, is used to solve alignment and leveling issues on motors, pumps, generators, and other types of machinery. These ultra-thin pieces of metal can precision level machinery quickly and easily. Zoro also has a super selection of plug gauges, gauge blocks and clamps, precision measuring accessories, ring gauges, and thickness gauges.
