It features a full ball contact style that allows the technician to expand the measuring element inside the opening and transfer the reading to an outside micrometer or caliper for an accurate diameter reading. With a measurement range of 0.2 to 0.3 inches and a 3 inch overall length, this gage suits tight, shallow holes where larger tools cannot reach. Machinists, tool and die technicians, and precision tradespeople rely on this type of gage for quality inspection and close-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspecting small drilled or reamed holes in metal components, checking valve guides, bushings, and similar bore features in maintenance and manufacturing environments. Its compact size makes it a practical addition to any precision measurement kit used in machine shop, maintenance, or field service applications where direct-reading bore gages are too large to fit the opening.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range of 0.2 to 0.3 inches for small bore applications\u003c\/li\u003e\n  \u003cli\u003eFull ball contact style for consistent seating inside the measured opening\u003c\/li\u003e\n  \u003cli\u003e3 inch overall length provides clearance and control during transfer measurement\u003c\/li\u003e\n  \u003cli\u003eTransfer-style measurement works with outside micrometers or calipers\u003c\/li\u003e\n  \u003cli\u003eCompact form factor reaches shallow or tightly spaced holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard small hole gage for use wherever transfer-style internal measurements in the 0.2 to 0.3 inch range are required.

Insert the ball end into the hole, expand the contact element with the knurled thimble until light drag is felt, then lock and withdraw before transferring to the reference measuring tool. Keep the contact surfaces clean and free of burrs or debris to avoid false readings. Handle with care to avoid dropping, which can damage the precision ball contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.2 to 0.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Style\u003c\/strong\u003e: Full Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.016 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 53071\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541547811122,"sku":"53071","price":80.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5e4b67e0d4f272cd9ad6cd8035b82c1.jpg?v=1785879079","url":"https:\/\/voomisupply.com\/products\/starrett-53071-small-hole-gage-0-2-to-0-3-inch-full-ball","provider":"Voomi Supply","version":"1.0","type":"link"}
