One end carries the Go member; the opposite end carries the No Go member. When the Go end passes fully and the No Go end does not enter, the threaded hole meets 2B specification. The gage is manufactured from steel for durability and dimensional stability under repeated use. A handle is included and sized at Handle Size 1, making it ready to use out of the box. Traceability documentation traceable to NIST standards is included, supporting quality-assurance and calibration recordkeeping requirements.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in machining, assembly, and inspection environments where 5\/16-24 threaded holes must be verified for conformance before components are accepted or released. Typical applications include incoming inspection of threaded fastener holes, in-process thread verification on production parts, and final inspection in quality-control departments. Trades and shops that commonly use this tool include precision machinists, mechanical assemblers, maintenance technicians, and quality inspectors working with fine-thread fastener applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design combines Go and No Go members in a single tool for efficient pass\/fail inspection\u003c\/li\u003e\n  \u003cli\u003eCalibrated to 5\/16-24 UNF thread form at 2B tolerance class\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable traceability certification included for quality recordkeeping\u003c\/li\u003e\n  \u003cli\u003eHandle Size 1 included — no additional handle purchase required\u003c\/li\u003e\n  \u003cli\u003eWeighs 1 pound — lightweight for bench or floor use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to inspect internal 5\/16-24 UNF threaded holes held to ANSI\/ASME 2B tolerance class.

Clean chips and cutting fluid from the hole before gaging to avoid false readings and gage wear. Store the gage in its case when not in use to protect the thread members from damage. Periodic recalibration against a certified setting plug is recommended to maintain measurement integrity; follow your facility calibration schedule and retain the included NIST-traceable certificate for audit purposes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go \/ No Go Plug Thread Gage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double 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: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Standard\u003c\/strong\u003e: 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: 34-383-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722187505970,"sku":"34-383-0","price":157.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9057c3561410b8e0518b0345ad0b2d2.jpg?v=1788587023","url":"https:\/\/voomisupply.com\/products\/spi-34-383-0-plug-thread-gage-5-16-24-2b-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
