Built with a flat steel leg and a polished finish, this caliper measures up to 4 inches (100 mm) maximum. The spring-joint mechanism keeps consistent tension on the legs, and the quick-nut adjustment allows fast, repeatable setting without losing your measurement. At 0.12 pounds, it is a compact, lightweight hand tool suited for machinists, pipefitters, and maintenance technicians who need reliable inside-dimension transfer work.\u003c\/p\u003e\u003cp\u003eThis inside caliper is used wherever a technician needs to measure bore diameters, inside pipe dimensions, or other internal clearances. It is appropriate for both shop and field use in plumbing, mechanical, and general maintenance environments. The flat leg profile reaches into tight bores cleanly, and the polished steel finish resists light corrosion during normal handling. Typical applications include checking pipe bore ID, fitting clearances, and verifying machined inside dimensions during fabrication or repair work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpring-joint design maintains consistent leg tension for stable measurements\u003c\/li\u003e\n\u003cli\u003eQuick-nut adjustment for fast, precise leg setting\u003c\/li\u003e\n\u003cli\u003eFlat leg profile for access to tight inside diameters\u003c\/li\u003e\n\u003cli\u003eMeasures up to 4 inches (100 mm) maximum inside diameter\u003c\/li\u003e\n\u003cli\u003ePolished steel construction for durability and corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose inside caliper suitable for standard measurement and layout tasks in machining, plumbing, and mechanical maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInside calipers are hand tools that require no installation. Set the leg spread to the desired measurement using the quick-nut adjustment before transferring to a rule or micrometer for reading. Handle with care to preserve leg tip geometry, as bent or worn tips reduce measurement accuracy. Store in a dry location to protect the polished steel finish from corrosion.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Type\u003c\/strong\u003e: Inside\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeg Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJoint Type\u003c\/strong\u003e: Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 4 inches (100 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick Nut Adjustment\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ID\/4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700776272178,"sku":"ID\/4","price":20.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5e5c4cde6e48d7f9bd3513de1be4e08.jpg?v=1788395169","url":"https:\/\/voomisupply.com\/products\/value-collection-id-4-inside-caliper-4-inch-spring-joint","provider":"Voomi Supply","version":"1.0","type":"link"}
