A thickness gauge is a tool to check the size of the gap. With a straight edge ruler and a set of gauges, one can check the flatness of a large surface. Or check the straightness of a long part.
A feeler gauge is used to fill gaps with specified dimensions during assembly or machining.
Because they are instruments capable of measuring quickly and accurately through comparison. Therefore, they are widely applied in industries such as the mechanical engineering industry, molds, metal processing, mechanical assembly.
Blades and shims are made of two materials, carbon steel or stainless steel.
