It is used to find the true size of holes, slots and recesses by transferring the dimension to a micrometer.\u003c\/p\u003e\u003cp\u003ePer the manufacturer, the ends of both contacts are hardened and ground to a radius to give clearance in the smallest hole the gage will enter, and constant spring tension gives uniform contact pressure. Both plungers lock at any setting, and the handle is rigidly attached to the contact plungers and self-centering. The final hole size is taken by measuring over the contacts with a micrometer (not included). Sold as a single gage.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eRange 1-1\/4 to 2-1\/8 in (32-54 mm), 2-3\/8 in (60 mm) handle\u003c\/li\u003e\u003cli\u003eTwo telescoping contacts\u003c\/li\u003e\u003cli\u003eContact ends hardened and ground to a radius, per the manufacturer\u003c\/li\u003e\u003cli\u003ePrecision ground radius on each contact gives two-point contact\u003c\/li\u003e\u003cli\u003eConstant spring tension for uniform contact pressure\u003c\/li\u003e\u003cli\u003eBoth plungers lock at any desired setting\u003c\/li\u003e\u003cli\u003eHandle rigidly attached to the plungers and self-centering\u003c\/li\u003e\u003cli\u003eFinal size read by measuring over the contacts with a micrometer (not included)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003cthead\u003e\u003ctr\u003e\u003cth\u003eSpecification\u003c\/th\u003e\u003cth\u003eValue\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd\u003eModel\u003c\/td\u003e\u003ctd\u003e579D\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eQuantity\u003c\/td\u003e\u003ctd\u003e1 piece\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eType\u003c\/td\u003e\u003ctd\u003etelescoping gage\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eRange\u003c\/td\u003e\u003ctd\u003e1-1\/4 to 2-1\/8 in (32-54 mm)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eHandle length\u003c\/td\u003e\u003ctd\u003e2-3\/8 in (60 mm)\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003ePart numbers\u003c\/h3\u003e\u003ctable\u003e\u003cthead\u003e\u003ctr\u003e\u003cth\u003eManufacturer part number (MPN)\u003c\/th\u003e\u003cth\u003eBig Papa SKU\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd\u003e579D\u003c\/td\u003e\u003ctd\u003eBP-G-STT-579D\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDocuments\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href='https:\/\/www.starrett.com\/products\/precision-measuring-tools\/precision-hand-tools\/hole-gages\/telescoping-gages\/579D' target='_blank' rel='noopener'\u003eManufacturer data sheet\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Starrett","offers":[{"title":"Default Title","offer_id":67592491925718,"sku":"BP-G-STT-579D","price":71.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/8595\/3494\/files\/579DcUSp1__06162.1791627488.webp?v=1791866960","url":"https:\/\/bigpapaentreprise.com\/en\/products\/starrett-579d-calibres-et-jauges","provider":"Big Papa Enterprise Ltd","version":"1.0","type":"link"}
