The contact tip is a 0.078-inch diameter steel ball mounted on a shaft with an overall contact point length of 0.671 inches. This replacement contact point threads into compatible test indicator spindles, restoring measurement accuracy without replacing the full instrument. It is installed by metrology technicians, quality control personnel, and machinists who require reliable surface contact geometry for runout, flatness, and bore measurement work.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for inspection and layout tasks on machine tools, surface plates, and fixtures where a ball-tip stylus provides consistent contact on curved, angled, or irregular surfaces. The steel construction offers durability for repetitive contact in shop-floor environments. It is a direct-fit replacement accessory for Teclock test indicators requiring a standard ball-style tip.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.078-inch (2.00 mm) diameter steel ball tip for accurate point contact on varied surfaces\u003c\/li\u003e\n  \u003cli\u003e0.671-inch overall contact point length for standard indicator fitment\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repeated-contact measurement cycles\u003c\/li\u003e\n  \u003cli\u003eDrop-in replacement restores indicator function without full instrument replacement\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.1 pounds for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Teclock test indicators requiring a ball-style contact point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eContact point replacement is performed by metrology or QC technicians. Remove the existing contact point by unscrewing it from the indicator spindle before threading in the replacement — do not force or cross-thread the tip. Handle the ball tip carefully to avoid surface damage that could affect measurement accuracy. Verify indicator calibration after installing a new contact point.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.078 inches (2.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.671 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Steel\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\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: 20-655-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699921322290,"sku":"20-655-7","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bc1b55e583ecdd08efbab979aac3d34.jpg?v=1788383469","url":"https:\/\/voomisupply.com\/products\/spi-20-655-7-test-indicator-ball-contact-point-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
