Machined from black granite, this plate provides a stable, flat reference surface for layout, inspection, and gauging tasks. The 640-0101 measures 12 inches long by 9 inches wide and 2 inches thick, with an overall unilateral flatness tolerance of 0.0002 inches. A certificate of conformance is included. The no-ledge configuration keeps the working surface unobstructed, making it well suited for a range of inspection setups used by machinists, quality technicians, and tool room personnel.\u003c\/p\u003e\n\u003cp\u003eThis surface plate is intended for use in machine shops, quality control labs, and tool rooms where a reliable flat reference is required for part inspection, layout marking, and precision gauging. The B Grade designation indicates suitability for general-purpose inspection work. The manageable footprint and 30-pound weight make this plate practical for benchtop installation at a fixed inspection station.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eB Grade flatness with 0.0002-inch unilateral tolerance for general-purpose inspection\u003c\/li\u003e\n  \u003cli\u003eBlack granite construction provides a stable, non-magnetic reference surface\u003c\/li\u003e\n  \u003cli\u003eNo-ledge design keeps the full working surface clear and accessible\u003c\/li\u003e\n  \u003cli\u003e12 inches x 9 inches x 2 inches overall dimensions suit benchtop use\u003c\/li\u003e\n  \u003cli\u003eCertificate of conformance included for quality documentation requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose B Grade inspection surface plate for benchtop dimensional measurement, layout, and gauging applications in machine shop and quality control environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSurface plates should be installed by a machinist or quality technician on a stable, level bench or stand rated to support the plate weight of 30 pounds. Before placing the plate, confirm the support surface is flat and free of debris that could cause uneven bearing. Avoid dropping or impacting the granite, as chipping or cracking will compromise flatness. Periodic recalibration against a certified reference standard is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Granite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Unilateral Flatness Tolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlate Type\u003c\/strong\u003e: No Ledge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 30 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Certificate of Conformance\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 640-0101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694999798066,"sku":"640-0101","price":90.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b83fd276b414b036b4455a984e9bf6c.jpg?v=1788330347","url":"https:\/\/voomisupply.com\/products\/value-collection-640-0101-granite-inspection-surface-plate","provider":"Voomi Supply","version":"1.0","type":"link"}
