3-Pack Stainless Steel Thread Measuring Wires by TWA

These Thread Measuring Wires, when used with a micrometer, swiftly and precisely measure the pitch diameters of external threads. Ideal for calibrating and inspecting thread plug gages for wear, these wires are meticulously calibrated to within .000005" of their labeled size. They maintain a tolerance of .000020" from the optimal wire diameter for the specified threads per inch. Boasting a roundness of .00010" and a taper not exceeding .00010", these wires are 2" in length and packaged in sets of three within a screw-top vial. With a minimum hardness of RC 62.5 and a surface finish of lapped, 1 MU AA, these wires surpass Federal specifications ASME/ANSI B1.2 and B1.6M, and come with a free NIST certificate of accuracy.
