It reads from 0 to 1 inch with a graduation of 0.001 inches, providing the resolution needed for sheet metal, gaskets, shims, and similar flat stock. The 2.5-inch throat depth allows clearance to reach interior measurement points that a standard gage cannot access. The 2.25-inch dial diameter makes the reading easy to view in the field. A jewel bearing movement supports repeatable, low-friction readings over extended service life. Licensed machinists, HVAC technicians, and sheet-metal workers are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThe 53121 suits residential and light commercial trade work wherever flat material thickness must be verified quickly and accurately. Typical applications include checking sheet metal stock, gasket material, insulation board, and rubber seals before installation. The flat contact surfaces and continuous dial make it straightforward to use on any flat or near-flat workpiece. Its portable form factor means it travels easily in a tool bag without requiring a bench setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 1 inch measurement range with 0.001 inch graduation for precise readings\u003c\/li\u003e\n  \u003cli\u003e2.5 inch throat depth for reaching interior measurement locations\u003c\/li\u003e\n  \u003cli\u003e2.25 inch dial diameter for clear, easy-to-read display\u003c\/li\u003e\n  \u003cli\u003eJewel bearing movement for smooth, repeatable operation\u003c\/li\u003e\n  \u003cli\u003eContinuous dial with balanced 0-100 dial reading scale\u003c\/li\u003e\n  \u003cli\u003eFlat contact tips with 0.25 inch contact diameter for consistent surface engagement\u003c\/li\u003e\n  \u003cli\u003ePortable design suited for field use without additional fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style dial thickness gage suitable for measuring flat stock, sheet material, gaskets, and shims in trade and light industrial environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this handheld measuring instrument. Before use, zero the dial against a known flat reference surface to confirm calibration. Keep contact faces clean and free of debris to maintain measurement accuracy. Store the gage in a protective case when not in use to prevent damage to the dial mechanism and contact tips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlat Contact Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-100 continuous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Tip Shape\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Jewel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: California Proposition 65\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 53121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542384279858,"sku":"53121","price":689.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7023035cddb4b6dd40f6736a838a4b3f.jpg?v=1785899280","url":"https:\/\/voomisupply.com\/products\/starrett-53121-dial-thickness-gage-0-1-in-0-001-grad","provider":"Voomi Supply","version":"1.0","type":"link"}
