It checks that a tapped hole accepts a mating fastener within the specified tolerance limits. When the Go member passes through the threaded feature without forced engagement, the thread is confirmed to be within the minimum material condition. This gage is used by machinists, quality inspectors, and toolroom technicians performing in-process or final inspection on precision threaded components. Traceability documentation to NIST standards is included, supporting calibration records and quality system requirements.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspection of fine-pitch internal threads in small-diameter features, typical of instrumentation, electronics, and precision mechanical assemblies where a number 6-40 threaded fastener is specified. The single-end Go configuration fits a Size 00 handle, which is sold separately. It is used at inspection stations, on the shop floor, or in toolrooms wherever thread conformance to ANSI and NIST-traceable standards must be documented.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo member verifies internal threads are within the maximum material limit for a 6-40 thread form\u003c\/li\u003e\n  \u003cli\u003e6H tolerance class meets ANSI standard requirements for general-purpose internal threads\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for quality system and calibration documentation\u003c\/li\u003e\n  \u003cli\u003eSingle-end design accepts a Size 00 handle (handle not included)\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and NIST standards for plug thread gaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with a Size 00 thread gage handle, sold separately.

Before use, ensure the gage and workpiece threads are clean and free of chips or debris to prevent false readings or gage damage. Apply only hand force when inserting the Go member; forced engagement can damage the gage or the part. Store the gage in a protected case away from other tools to preserve calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Size\u003c\/strong\u003e: 00 (not included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34-229-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692836225330,"sku":"34-229-5","price":86.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c0bf1462fb94437c157b542dfcaf16e.jpg?v=1788303769","url":"https:\/\/voomisupply.com\/products\/spi-34-229-5-plug-thread-gage-6-40-6h-single-end-go","provider":"Voomi Supply","version":"1.0","type":"link"}
