The jaw depth measures 1.57 inches, making it suitable for reaching into slots, steps, and recesses commonly encountered in mechanical and fabrication work. The caliper ships NIST-traceable calibrated, so it is ready for use on jobs where documented traceability is required. A single set screw locks the jaw position during reading. A protective case is included for storage and transport. This tool is used by machinists, pipefitters, HVAC technicians, and other trade professionals who need reliable, repeatable linear measurement in the field or shop.\u003c\/p\u003e\u003cp\u003eThe CMS170309001 is well suited for residential and commercial service work where precise inside, outside, depth, and step measurements are required. Its stainless steel construction resists corrosion in wet or chemically active environments typical of plumbing, HVAC, and mechanical rooms. The 6-inch maximum range covers the majority of pipe diameters, fitting dimensions, and component measurements encountered in day-to-day trade service. The dual-scale graduation supports both inch and metric readings, with a 0.02 millimeter metric graduation alongside the 0.001 inch inch-scale graduation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 6 inch measurement range with 0.001 inch accuracy\u003c\/li\u003e\n\u003cli\u003eStainless steel construction resists corrosion and wear\u003c\/li\u003e\n\u003cli\u003eNIST-traceable calibration included out of the box\u003c\/li\u003e\n\u003cli\u003e1.57 inch jaw depth for recessed and stepped measurements\u003c\/li\u003e\n\u003cli\u003eDual scale: 0.001 inch graduation and 0.02 millimeter graduation\u003c\/li\u003e\n\u003cli\u003eSingle set screw jaw lock for stable readings\u003c\/li\u003e\n\u003cli\u003eIncludes protective carrying case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose vernier caliper suitable for precision linear measurement tasks across HVAC, plumbing, mechanical, and fabrication applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eVernier calipers require no installation but should be zeroed and inspected before use to confirm jaw faces are clean and fully closed at the zero mark. Handle stainless steel measuring tools with clean, dry hands to prevent corrosion from skin oils over time. Store the caliper in its included case when not in use to protect the measuring surfaces and graduated scales from damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 6 inches (0 to 150 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation (Inch)\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation (Metric)\u003c\/strong\u003e: 0.02 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Depth\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Screws\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.88 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8 inches x 3 inches x 1 inch\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: CMS170309001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690569564466,"sku":"CMS170309001","price":66.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/281adbb7b59f445e613b15e8e3bab683.jpg?v=1788271868","url":"https:\/\/voomisupply.com\/products\/spi-cms170309001-vernier-caliper-0-6-in-stainless-nist","provider":"Voomi Supply","version":"1.0","type":"link"}
