This wire is sized for 14 TPI threads with a 0.07-inch pitch and measures 2.25 inches in length. The nominal best wire diameter is 0.04124 inches, and the nominal constant is 0.0631 inches. Sold in a set of 3 pieces, it is used with the three-wire method to determine the pitch diameter of threaded components. Machinists, quality control technicians, and tool room professionals rely on this wire for traceable, repeatable measurement results.\u003c\/p\u003e\u003cp\u003eThis measuring wire is intended for use with thread plug gages and is suited to inspection environments where precise pitch diameter verification is required. It fits standard 14 TPI thread forms and is applicable in both production and toolroom settings where thread gauge verification or acceptance inspection is performed. The three-piece set supports the standard three-wire measurement method on external threads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSized for 14 TPI threads with a 0.07-inch pitch\u003c\/li\u003e\n\u003cli\u003eNominal best wire diameter of 0.04124 inches for accurate seating in thread groove\u003c\/li\u003e\n\u003cli\u003eNominal constant of 0.0631 inches supports direct pitch diameter calculation\u003c\/li\u003e\n\u003cli\u003eWire length of 2.25 inches provides adequate working length for most thread gaging setups\u003c\/li\u003e\n\u003cli\u003eSet of 3 pieces supports the standard three-wire measurement method\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 on 14 TPI threaded components using the three-wire pitch diameter measurement method.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread measuring wires are used by quality technicians and machinists during inspection, not installation. Handle wires carefully to avoid nicks or bends that would affect measurement accuracy. Use with a micrometer and the appropriate three-wire constant formula to calculate pitch diameter. Store wires in their case when not in use to protect the precision surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 14 TPI, 0.07 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Best Wire Diameter\u003c\/strong\u003e: 0.04124 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Constant\u003c\/strong\u003e: 0.0631 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePieces per Set\u003c\/strong\u003e: 3\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: 64AAA224\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559500218674,"sku":"64AAA224","price":288.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8eba27387717d9fcebcf334515511b42_cea60da0-4c66-43d4-a7bd-0031da14901e.jpg?v=1786433998","url":"https:\/\/voomisupply.com\/products\/mitutoyo-64aaa224-thread-pitch-diameter-measuring-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
