Finished in a satin chrome-plated coating, it provides clear contrast against scribed lines and resists glare under shop lighting. The rule carries a 4R graduation style, offering four scales on a single blade: 1\/16, 1\/32, 1\/64, and 1\/8 inch. At 0.0400 inches thick, the blade lies flat against a workpiece without flexing. Machinists, tool and die makers, pipefitters, and sheet metal workers reach for this rule as a reliable bench and layout measuring tool.\u003c\/p\u003e\u003cp\u003eThe 13-846-1 is suited to precision layout and inspection work in machine shops, fabrication shops, and industrial maintenance environments. The horizontal scale orientation makes it straightforward to read measurements directly without rotating the rule. The rigid construction supports accurate scribe-line transfers and depth measurements off a reference surface. It installs and functions without additional hardware or setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4R graduation style provides four measurement scales on one blade: 1\/16, 1\/32, 1\/64, and 1\/8 inch\u003c\/li\u003e\n\u003cli\u003eRigid steel blade does not flex during layout or measurement tasks\u003c\/li\u003e\n\u003cli\u003eSatin chrome-plated finish reduces glare and improves scale readability\u003c\/li\u003e\n\u003cli\u003e12-inch overall length covers common layout and inspection ranges\u003c\/li\u003e\n\u003cli\u003e1-inch blade width accommodates all four graduation scales without crowding\u003c\/li\u003e\n\u003cli\u003eNon-magnetic, no hook included — clean, straightforward reference tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 12-inch rigid steel rule for general precision layout and measurement use in machining, fabrication, and industrial trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this hand measuring tool. Store the rule flat or in a dedicated sleeve to protect the graduation markings from wear. Avoid using the rule as a cutting guide with rotary tools, as contact with blades can damage the etched scales. Periodic wiping with a light machine oil will help maintain the chrome finish and prevent surface rust.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 4R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation Scales\u003c\/strong\u003e: 1\/16, 1\/32, 1\/64, 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Satin Chrome-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Hook\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 13-846-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51707256373554,"sku":"13-846-1","price":39.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3fd8e0e7cd5d5be3d3d2ab912b15610.jpg?v=1788439233","url":"https:\/\/voomisupply.com\/products\/spi-13-846-1-steel-rule-12-inch-4r-rigid","provider":"Voomi Supply","version":"1.0","type":"link"}
