The gauge covers a range of 12 to 40 threads per inch (TPI), making it suitable for a wide range of standard fractional thread forms encountered in mechanical, plumbing, and HVAC work. Sold as a package of 2 gauges, it gives technicians a reliable reference tool for confirming thread counts before selecting taps, dies, or threaded fittings. At 0.1 pounds, it is compact and easy to carry in a tool bag or service kit.\u003c\/p\u003e\n\u003cp\u003eThis pitch gauge is used in trade and maintenance applications where technicians need to quickly identify unknown thread pitches on pipe fittings, fasteners, and mechanical components. It is appropriate for residential and light commercial service work involving fractional inch threads, which are common in domestic plumbing, HVAC equipment fasteners, and general mechanical assemblies. Licensed tradespeople and experienced service technicians use pitch gauges during diagnosis, repair, and parts sourcing to avoid thread mismatch errors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCovers 12 to 40 TPI range for fractional inch threads\u003c\/li\u003e\n  \u003cli\u003ePackaged as a set of 2 gauges per unit\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for easy portability in a tool bag\u003c\/li\u003e\n  \u003cli\u003eProvides a direct physical reference for confirming thread pitch before parts selection\u003c\/li\u003e\n  \u003cli\u003eUseful across plumbing, HVAC, and mechanical service applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard fractional inch threaded fasteners and fittings in the 12 to 40 TPI range, consistent with common thread forms found in residential and light commercial mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this tool. To use, select a blade from the gauge set and align its teeth against the thread profile of the fastener or fitting being measured. Work with the system depressurized and de-energized when measuring threads on components that are part of an active system. Store the gauge in a dry location to prevent corrosion of the measuring blades.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Range\u003c\/strong\u003e: 12-40 threads per inch (TPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Fractional inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: CENTURY DRILL TOOL CO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 98401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51561003188530,"sku":"98401","price":26.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c8519af9733229ba77eb5e8979ca6e1.jpg?v=1786461105","url":"https:\/\/voomisupply.com\/products\/century-drill-tool-co-inc-98401-fractional-pitch-gauge","provider":"Voomi Supply","version":"1.0","type":"link"}
