Each leaf is stamped with its corresponding pitch value, allowing a technician to fan through the set and match the leaf to a threaded fastener or tapped hole until a flush fit is achieved. The thread angle is 60 degrees, which corresponds to standard Unified National thread forms (UN, UNC, UNF, UNEF). The leaves are constructed from steel for durability in shop environments.\u003c\/p\u003e\n\u003cp\u003eThis gage set is suited for use in machine shops, maintenance facilities, fabrication shops, and field service applications where identifying unknown thread pitch on fasteners, fittings, or tapped components is required. Plumbers, pipefitters, machinists, and mechanical contractors use pitch gages when sorting mixed fastener stock, verifying thread form before assembly, or identifying replacement hardware. The 18-leaf configuration covers a practical range of common inch thread pitches without requiring a separate gage set for coarse and fine series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 leaves cover a broad range of standard inch thread pitches in a single set\u003c\/li\u003e\n  \u003cli\u003e60-degree thread angle matches Unified National (UN) thread form standards\u003c\/li\u003e\n  \u003cli\u003eMeasures both external threads (bolts, studs, screws) and internal threads (nuts, tapped holes)\u003c\/li\u003e\n  \u003cli\u003eSteel leaf construction for resistance to wear in shop use\u003c\/li\u003e\n  \u003cli\u003eCompact folding format keeps leaves organized and protected when not in use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for measuring inch-series threads with a 60-degree thread angle, consistent with Unified National thread standards used on standard fasteners and fittings in general mechanical and trade applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this measuring tool. To use, fan the leaves and select the one that best matches the thread spacing of the fastener or tapped hole, checking for a flush, gap-free fit against the thread flanks. Wipe leaves clean after use and avoid bending or forcing leaves against damaged threads, as this can deform the thin steel and reduce gage accuracy. Store the set folded and away from coolants or corrosive fluids to maintain leaf condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Leaves\u003c\/strong\u003e: 18\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Mechanism\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 22290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704371118386,"sku":"22290","price":31.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21e85393003bf8574aa5c37314ef91da.jpg?v=1788422442","url":"https:\/\/voomisupply.com\/products\/value-collection-22290-screw-pitch-gage-18-leaf-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
