It features a single spindle with a 12-inch spindle length, giving technicians and machinists sufficient reach for scribing lines and transferring measurements across workpieces. The base measures 3.5 inches long by 3.1875 inches wide and is constructed from hardened steel for durability and resistance to wear. This tool is suited for machine shops, fabrication environments, and maintenance settings where accurate surface layout work is required.\u003c\/p\u003e\u003cp\u003eThe STARRETT 51242 is used in precision metalworking and machining applications where a stable, adjustable scribing reference is needed. It performs well on surface plates, mill tables, and flat reference surfaces. Machinists, toolmakers, and maintenance technicians working in industrial or production settings will find this gage appropriate for layout lines, height transfer, and part inspection tasks. It is a standard single-spindle configuration well suited to general-purpose surface work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle spindle configuration with 12-inch spindle length for extended reach during layout work\u003c\/li\u003e\n\u003cli\u003eHardened steel base construction for long-term wear resistance on work surfaces\u003c\/li\u003e\n\u003cli\u003eBase dimensions of 3.5 inches long by 3.1875 inches wide provide stable footing on flat reference surfaces\u003c\/li\u003e\n\u003cli\u003eCompact base profile suits use on surface plates and machine tables\u003c\/li\u003e\n\u003cli\u003eStandard single-spindle design compatible with typical scriber and indicator accessories\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-spindle surface gage suitable for general precision layout and inspection use on flat reference surfaces in machining and fabrication environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface gages are set up and used by machinists, toolmakers, and maintenance technicians and require no permanent installation. Ensure the reference surface or surface plate is clean and free of burrs before placing the gage. The spindle should be adjusted and locked at the desired height before scribing or transferring a measurement. Handle the hardened steel base carefully to avoid nicking the contact surface, which would affect accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Spindles\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 3.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.438 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41114508\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: 51242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538958483762,"sku":"51242","price":447.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02d0938d3114301fccd1825e66007bb5.jpg?v=1785830916","url":"https:\/\/voomisupply.com\/products\/starrett-51242-surface-gage-1-spindle-12-inch-spindle","provider":"Voomi Supply","version":"1.0","type":"link"}
