Designed for 27 TPI threads with a 0.04 inch pitch, this wire has a nominal best wire diameter of 0.02138 inches and a nominal constant of 0.0295 inches. Each wire measures 1.125 inches in length. The set includes 2 pieces. Machinists, tool and die makers, and quality control technicians use these wires with a micrometer and the three-wire method to achieve accurate pitch diameter measurements on threaded components.\u003c\/p\u003e\u003cp\u003eThis measuring wire is intended for use with thread plug gages and related threadform inspection tasks. The three-wire method is a standard technique in precision machining environments where direct pitch diameter measurement is required for compliance with thread standards. These wires are suited for shop floor and inspection room use wherever 27 TPI unified or similar thread forms must be verified to close tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e27 TPI thread compatibility with 0.04 inch pitch\u003c\/li\u003e\n\u003cli\u003eNominal best wire diameter of 0.02138 inches for accurate three-wire calculations\u003c\/li\u003e\n\u003cli\u003eNominal constant of 0.0295 inches simplifies micrometer reading conversion\u003c\/li\u003e\n\u003cli\u003eWire length of 1.125 inches provides adequate handling for gage setups\u003c\/li\u003e\n\u003cli\u003eSet of 2 wires included for standard three-wire method application\u003c\/li\u003e\n\u003cli\u003eDesigned for use with thread plug gages\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with thread plug gages for pitch diameter measurement of 27 TPI threaded components using the three-wire method.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread measuring wires are used by machinists and quality technicians and require no permanent installation. Place wires in the thread grooves and use a calibrated micrometer to take the measurement across the wires, then apply the nominal constant to determine pitch diameter. Handle wires carefully to avoid nicks or deformation that would affect measurement accuracy. Store wires in their original container when not in use to maintain surface condition.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 27 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch (Decimal Inch)\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Best Wire Diameter\u003c\/strong\u003e: 0.02138 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Constant\u003c\/strong\u003e: 0.0295 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Included\u003c\/strong\u003e: 2 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Thread Plug Gage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 64AAA217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51564136726834,"sku":"64AAA217","price":289.96,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8eba27387717d9fcebcf334515511b42_ee4e8369-a63e-4401-b58d-24f21df49a1f.jpg?v=1786511979","url":"https:\/\/voomisupply.com\/products\/mitutoyo-64aaa217-thread-pitch-diameter-measuring-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
