The body is constructed from hardened tool steel, providing the rigidity and wear resistance required for consistent shop-floor use. A white dial face delivers clear, high-contrast readings in varying light conditions. This gage is used by machinists, sheet metal fabricators, aerospace technicians, and precision assembly trades to verify countersink dimensions before fastener installation. It ships with a set master ring for calibration at setup.\u003c\/p\u003e\u003cp\u003eThis instrument is suited for inspecting 100-degree countersunk holes in metal, composite, and sheet goods where fastener flushness and seating angle are critical. Typical applications include aircraft skin panels, structural assemblies, and precision machined components where countersink diameter must fall within a defined tolerance. The included set master ring allows the technician to zero the gage before beginning a measurement run, reducing setup error and improving repeatability across a production batch.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 0.02 to 0.17 inches covers small-diameter countersunk fastener holes\u003c\/li\u003e\n\u003cli\u003e100-degree countersink angle matches standard aerospace and general-purpose countersink geometry\u003c\/li\u003e\n\u003cli\u003eHardened tool steel construction resists wear and maintains calibration under frequent use\u003c\/li\u003e\n\u003cli\u003eWhite dial face provides high-contrast readability in shop environments\u003c\/li\u003e\n\u003cli\u003eIncludes set master ring for on-the-spot calibration and zeroing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 100-degree countersunk holes in the 0.02 to 0.17 inch diameter range, consistent with standard countersink gage applications in precision machining and fabrication.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis is a precision measuring instrument, not an installed component. Handle with care to avoid dropping or impact that could affect calibration. Always zero the gage against the included set master ring before taking measurements. Store in a protective case when not in use to preserve the hardened tool steel surfaces and dial mechanism.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.02 to 0.17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountersink Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hardened Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Face Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Set Master Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63706\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539148702002,"sku":"63706","price":970.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd78838d2b352b2b02b74d3e988c9396.jpg?v=1785835465","url":"https:\/\/voomisupply.com\/products\/starrett-63706-countersink-gage-0-02-0-17-in-100-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
