Machined from steel, this contact point features an M1.7 x 0.35 thread and measures 3 mm in diameter with a contact point length of 37.4 mm (approximately 1.47 inches). It is used by metrologists, machinists, and quality control technicians to take accurate displacement and runout readings in both shop-floor and inspection environments. The steel construction provides durability and consistent contact geometry across repeated measurements.\u003c\/p\u003e\u003cp\u003eThis contact point is compatible with the 513-512 Pocket Type Dial Test Indicator and is suited for applications requiring precise positional measurement in tight or recessed areas. Its universal geometry supports measurement in multiple directions, making it appropriate for surface deviation checks, bore alignment, and feature-to-feature comparisons in precision machining and quality assurance workflows.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel construction for durability and wear resistance during repeated contact\u003c\/li\u003e\n\u003cli\u003eM1.7 x 0.35 thread for secure attachment to compatible indicator spindles\u003c\/li\u003e\n\u003cli\u003e3 mm tip diameter for stable, repeatable contact surface\u003c\/li\u003e\n\u003cli\u003e37.4 mm contact point length for reach into recessed or hard-to-access measurement areas\u003c\/li\u003e\n\u003cli\u003eSupports direction-of-measurement and direction-of-measuring-point flexibility for universal application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the MITUTOYO 513-512 Pocket Type Dial Test Indicator.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContact point replacement is performed by qualified metrology or machine shop personnel using appropriate thread engagement for M1.7 x 0.35 spindle connections. Handle the contact tip carefully to avoid surface damage that could affect measurement accuracy. Do not overtighten the contact point onto the indicator spindle, as this can damage the thread or alter stylus alignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M1.7 x 0.35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Diameter\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 37.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 131317\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563631968562,"sku":"131317","price":23.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59ce5285dcc4c5a7a856d5603a214aac.jpg?v=1786499958","url":"https:\/\/voomisupply.com\/products\/mitutoyo-131317-drop-indicator-contact-point-3mm-37-4mm","provider":"Voomi Supply","version":"1.0","type":"link"}
