The gage covers a pitch range of 0.25 to 0.60mm and a threads-per-inch (TPI) range of 40 to 64, making it suitable for both metric and inch thread systems. Leaves are stamped from stainless steel for corrosion resistance and long service life. Machinists, pipefitters, and maintenance technicians use this tool during thread inspection, fastener identification, and repair work where confirming thread pitch is required before assembly or re-tapping.\u003c\/p\u003e\n\u003cp\u003eThis pitch gage is suited for shop floor, field service, and maintenance environments where quick thread identification is needed across a range of fine-pitch fastener applications. The dual measurement capability covers 60-degree thread forms standard to most unified inch and metric thread systems. At 0.5 pounds, it is compact enough for a toolbox or service bag. Both external and internal thread locations are supported, which allows inspection of bolts, screws, nuts, and threaded bores with a single tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21 individual leaves provide coverage across 0.25 to 0.60mm pitch range and 40 to 64 TPI range\u003c\/li\u003e\n  \u003cli\u003eDual inch and metric measurement capability in one gage\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists corrosion and wear during regular use\u003c\/li\u003e\n  \u003cli\u003e60-degree thread angle matches the geometry of standard unified and metric thread forms\u003c\/li\u003e\n  \u003cli\u003eChecks both external and internal thread locations\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.5 pounds for easy portability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 60-degree external and internal threads conforming to standard unified inch and metric thread systems across the supported pitch and TPI ranges.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this hand-held inspection tool. Select the appropriate leaf and align it carefully with the thread being measured under adequate lighting to ensure accurate pitch identification. Keep the gage clean and dry after use to preserve leaf condition and measurement accuracy. Do not force leaves against threads, as this can deform the stamped profiles and reduce gage reliability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Leaves\u003c\/strong\u003e: 21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 0.25 to 0.60mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch Range\u003c\/strong\u003e: 40 to 64 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Inch and Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Location\u003c\/strong\u003e: External and Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TH-COM-S-NR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707632746802,"sku":"TH-COM-S-NR","price":57.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/662f2ea99d218beaaf75d7017e703b04.jpg?v=1788441337","url":"https:\/\/voomisupply.com\/products\/value-collection-th-com-s-nr-screw-pitch-gage-21-leaf","provider":"Voomi Supply","version":"1.0","type":"link"}
