Built from tool steel, this single-ring gage checks 4-48 UNF (Unified National Fine) threads to Class 2A tolerance standards. It is used by machinists, quality control inspectors, and tool-room technicians to confirm that a threaded part will assemble correctly with its mating component. The Go gage must pass fully over the threaded workpiece for the part to be accepted. NIST-traceable standards govern its calibration, making it suitable for precision inspection environments where traceability documentation is required.\u003c\/p\u003e\u003cp\u003eThis gage applies to inspection of No. 4-48 UNF external threads, which are common in small fastener, instrument, and precision-assembly applications. Class 2A is the standard tolerance class for general-purpose threaded fasteners and covers the majority of commercially produced bolts, screws, and studs. A quality control technician or tool-room inspector would use this gage at incoming inspection, in-process checking, or final part acceptance stages.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo-type single ring gage verifies maximum material condition acceptance of external threads\u003c\/li\u003e\n\u003cli\u003e4-48 UNF thread form for fine-pitch No. 4 diameter applications\u003c\/li\u003e\n\u003cli\u003eClass 2A tolerance classification for general-purpose fastener inspection\u003c\/li\u003e\n\u003cli\u003eTool steel construction provides durability and wear resistance in production environments\u003c\/li\u003e\n\u003cli\u003eNIST-traceable standards compliance supports calibration documentation requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on external 4-48 UNF Class 2A threaded workpieces in accordance with Unified National Fine thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreaded ring gages are handled and used by machinists and quality control inspectors, not installed in a system. Keep the gage clean and lightly oiled when not in use to prevent corrosion and wear. Do not force the gage onto a thread; if resistance is felt, the part is out of tolerance or debris is present. Periodic recalibration against NIST-traceable masters is recommended to maintain measurement integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNF (Unified National Fine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Configuration\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VERMONT GAGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 361111010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51755437293874,"sku":"361111010","price":174.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_6ad31fac-b2ca-4640-8079-13522bb95216.jpg?v=1788955077","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361111010-threaded-ring-gage-4-48-unf-go","provider":"Voomi Supply","version":"1.0","type":"link"}
