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.
Wire Gauges. The gauge of a piece of wire is a measurement of its width (diameter). Gauge is often abbreviated as ga, thus 20 gauge = 20ga. There are two main gauge systems used to determine wire size for crafters and artisans. American Wire Gauge is typically (but not always) the way jewelry wire is measured in the United States and Canada. Standard Wire Gauge (SWG) is typically (but not always) the measurement system used in Great Britain.
