Martin Tschopp 501-055 Thread measuring wires with micrometer holder. Diameter 0.390mm/0.01535" Accuracy : 0.001mm/.00005'' Micrometer Spindle : 6 35mm For 0.65mm & 40TPI & 36TPI pitch Vee Blocks the Standard Force model andThread Measuring Wires with micrometer holders The three wire measuring process is one of the most precise procedures for determining the pitch diameter of threads. The M+T thread measuring wires with micrometer holders combine this procedure with unique handling ease measuring security of the highest order and absolute efficiency. The corresponding measuring wires position themselves after they have been affixed through the integrated washer springs
