Gage blocks serve as the physical reference standard in precision measurement workflows, providing a traceable baseline for calibrating micrometers, calipers, comparators, and surface plates. This block measures 5.00000 inches in nominal length and ships with NIST certification, confirming that its actual dimensions have been verified against national measurement standards. At 2 pounds, it is a solid, stable block suited for bench-level metrology work. Grade 0 indicates a higher accuracy class appropriate for calibration and inspection laboratory use rather than general shop-floor production gauging.\u003c\/p\u003e\n\u003cp\u003eThis gage block is used in calibration labs, tool rooms, quality control departments, and precision machine shops. A 5-inch block covers a range of setup and inspection tasks, including setting height gauges, verifying go\/no-go gauge dimensions, and establishing transfer measurements. It is appropriate for applications where a NIST-traceable reference is required by internal quality procedures or customer specifications. Metrology technicians, quality inspectors, and precision machinists are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 0 accuracy class for calibration and high-precision inspection use\u003c\/li\u003e\n  \u003cli\u003eNominal size of 5.00000 inches for versatile setup and reference work\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and long-term dimensional stability\u003c\/li\u003e\n  \u003cli\u003eIncludes NIST certification for traceable measurement documentation\u003c\/li\u003e\n  \u003cli\u003eRectangular form for stable, repeatable wringing and stacking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose rectangular gage block for use with standard gage block accessories including holders, jaw sets, and scribers compatible with Grade 0 steel blocks in the 5-inch size class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks require handling with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Blocks should be stored in a controlled-temperature environment and allowed to thermally stabilize before use. When wringing blocks together, apply light lateral pressure without forcing to avoid surface damage. Periodic recertification intervals should follow the facility quality management plan or applicable metrology standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 5.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: Grade 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\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: 630-25006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692151111986,"sku":"630-25006","price":334.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1f285ca2b9ff4c0c92601c0149956a0.jpg?v=1788293799","url":"https:\/\/voomisupply.com\/products\/value-collection-630-25006-steel-gage-block-5-in-grade-0","provider":"Voomi Supply","version":"1.0","type":"link"}
