The contact tip is formed from stainless steel and measures 0.078 inches in ball diameter with a contact point length of 0.8 inches. This replacement or spare contact point threads into the indicator spindle and provides a consistent, hard contact surface for runout checks, surface comparisons, and bore measurement work. Metrology technicians, machinists, and quality control personnel are the primary users. The stainless steel construction resists corrosion and maintains dimensional stability under repeated contact cycles.\u003c\/p\u003e\u003cp\u003eThis contact point is sized for use with the SPI Integral Series of test indicators. It is suited to precision shop environments including tool rooms, inspection departments, and CNC setup areas where dial test indicators are used to verify part geometry, fixture alignment, or machine axis repeatability. The 0.078 inch ball tip is appropriate for applications requiring contact on small radii, grooves, or contoured surfaces where a flat or chisel-style tip would not seat correctly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.078 inch stainless steel ball tip for consistent contact on curved and contoured surfaces\u003c\/li\u003e\n\u003cli\u003e0.8 inch contact point length provides reach for recessed features\u003c\/li\u003e\n\u003cli\u003eStainless steel construction resists corrosion and wear under repeated measurement cycles\u003c\/li\u003e\n\u003cli\u003eDesigned for use with SPI Integral Series test indicators\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.01 pounds for minimal indicator spindle loading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the SPI Integral Series of test indicators.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContact points are installed and removed by a licensed or trained metrology technician or machinist using the appropriate wrench or pin spanner for the indicator spindle thread. Handle the ball tip carefully to avoid nicking or contaminating the contact surface, as surface damage will affect measurement accuracy. Do not overtighten the contact point into the indicator spindle, as this can damage the thread or distort the tip geometry. Store contact points in a clean, dry location when not in use to protect the stainless steel surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 0.8 inches (20.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.078 inches (2.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 0.75 inches length x 0.13 inches width x 0.13 inches height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 22-001-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694586495282,"sku":"22-001-2","price":17.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71dec2da865e30d9136da0a29f994683.jpg?v=1788325837","url":"https:\/\/voomisupply.com\/products\/spi-22-001-2-test-indicator-ball-contact-point","provider":"Voomi Supply","version":"1.0","type":"link"}
