It features a steel construction with a 0.118 inch (3.00 mm) ball diameter and an overall contact point length of 1.336 inches. This replacement tip threads into compatible test indicators and provides a precision contact surface for measuring bores, slots, and hard-to-reach surfaces. It is a standard accessory used by machinists, quality control technicians, and metrology professionals in manufacturing and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis contact point is intended for use with Mitutoyo dial test indicators and serves applications where a spherical contact tip is needed to maintain accurate stylus contact on curved or irregular workpiece surfaces. Typical use cases include bore gauging, runout measurement, and surface deviation checks on production floors and in inspection labs. The steel tip provides durability under repeated contact cycling in high-volume measurement tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall diameter of 0.118 inches (3.00 mm) for precise point contact\u003c\/li\u003e\n  \u003cli\u003eOverall contact point length of 1.336 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with Mitutoyo test indicators\u003c\/li\u003e\n  \u003cli\u003eSold individually as a direct replacement contact tip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Mitutoyo test indicators.

Zero the indicator before seating the new contact point and confirm the tip is fully threaded and secure before use. Avoid overtightening, which can damage the indicator spindle threads. Handle the steel ball tip carefully to prevent nicks or surface damage that could affect measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.118 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 1.336 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20-311-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691149459762,"sku":"20-311-7","price":15.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67b8dd13222fc50b54d219995c7003d4.jpg?v=1788280837","url":"https:\/\/voomisupply.com\/products\/spi-20-311-7-ball-contact-point-steel-mitutoyo","provider":"Voomi Supply","version":"1.0","type":"link"}
