Measuring 18 inches in overall length and 1-1\/8 inches in overall width, this rule features a satin chrome-plated finish that reduces glare and resists wear. The 16R graduation style provides four incremental scales — 1\/32, 1\/64, 1\/50, and 1\/100 inch — giving machinists, fabricators, and layout technicians multiple measurement references on a single tool. At 0.0400 inches thick, the blade maintains flatness and rigidity throughout its length, supporting accurate readings in both bench and field applications.\u003c\/p\u003e\u003cp\u003eThis rule is suited for layout, inspection, and general measurement tasks in machine shops, fabrication facilities, and maintenance environments. The horizontal scale orientation supports straightforward left-to-right reading. It carries no hook and is non-magnetic, keeping it compatible with setups where magnetic interference or snagging would be a concern. Tradespeople and precision-measurement technicians working in metalworking, HVAC fabrication, or plumbing layout will find the multiple graduation scales practical for switching between fractional and decimal inch references without changing tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFour graduation scales on a single blade: 1\/32, 1\/64, 1\/50, and 1\/100 inch\u003c\/li\u003e\n\u003cli\u003eRigid construction maintains flatness across the full 18-inch length\u003c\/li\u003e\n\u003cli\u003eSatin chrome-plated finish reduces glare and protects against corrosion\u003c\/li\u003e\n\u003cli\u003e16R graduation style for versatile fractional and fine decimal measurement\u003c\/li\u003e\n\u003cli\u003eNon-magnetic blade suitable for use near sensitive components\u003c\/li\u003e\n\u003cli\u003eNo hook — clean straight edge for layout and scribing tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose rigid steel rule for bench measurement, layout, and inspection tasks across metalworking, fabrication, and trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis is a hand measurement tool and requires no installation. Store flat to preserve blade straightness. Keep the satin chrome surface clean and dry to maintain graduation legibility and corrosion resistance. Do not use as a cutting guide with high-force rotary tools, as this can damage graduation markings and compromise edge accuracy.\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: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-1\/8 inches\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: 16R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduations\u003c\/strong\u003e: 1\/32, 1\/64, 1\/50, 1\/100 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\u003eIncludes Hook\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic\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: 13-853-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690686611762,"sku":"13-853-7","price":47.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9ef32336f2c99cff2a0af130a8ccd06.jpg?v=1788273959","url":"https:\/\/voomisupply.com\/products\/spi-13-853-7-steel-rule-18-inch-rigid-16r-graduation","provider":"Voomi Supply","version":"1.0","type":"link"}
