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. They are flexible enough that, even if they are all on the same hinge, several can be stacked together to gauge intermediate values. sourcensave is an Online One Stop Shop for all feeler gauges and allows you to shop from a variety of Top Genuine Brands like Stanley, Groz etc. sourcensave aims to bring about a significant transformational change in the Indirect material supply chain by cutting down inefficiencies and bringing in predictability through a suite of value added services.
