Each leaf is stamped with its corresponding threads-per-inch value, allowing technicians to fan through the set and find a matching fit quickly. The gage covers a range of 4 to 84 TPI and is built for a 60-degree thread angle, which is the standard profile for Unified National threads. Constructed from steel with a locking mechanism to hold leaves open during use, this tool is suited for shop, field, and inspection work where accurate thread identification is required.\u003c\/p\u003e\n\u003cp\u003eThis screw pitch gage is used across mechanical, plumbing, HVAC, and electrical trades wherever threaded fasteners must be identified, matched, or specified. It works on both external threads such as bolts and studs and internal threads such as nuts and tapped holes. Typical applications include identifying replacement fastener specs during equipment repair, verifying thread pitch before tapping or re-threading, and quality checks on fabricated assemblies. The inch measurement type makes it appropriate for standard U.S. fastener stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e51 individual leaves covering 4 to 84 TPI for broad inch-thread coverage\u003c\/li\u003e\n  \u003cli\u003e60-degree thread angle matches Unified National thread standard profile\u003c\/li\u003e\n  \u003cli\u003eUsable on both external and internal thread locations\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and field environments\u003c\/li\u003e\n  \u003cli\u003eIntegrated locking mechanism holds selected leaf in position during measurement\u003c\/li\u003e\n  \u003cli\u003eCompact folding design keeps leaves protected when not in use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard inch-series Unified National thread forms on external and internal threaded fasteners and components across a range of 4 to 84 TPI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this hand tool. Technicians should power down or de-energize any equipment before measuring threads on components in live systems. Select a leaf, align it flush against the thread profile, and compare for a no-gap fit. Keep leaves clean and dry to maintain accurate seating against thread flanks.\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\u003eThreads per Inch Range\u003c\/strong\u003e: 4 to 84 TPI\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: 51\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 615-6351\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693469532466,"sku":"615-6351","price":43.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1af03ce0a403038c7e8d1d64bc212c7.jpg?v=1788312850","url":"https:\/\/voomisupply.com\/products\/value-collection-615-6351-screw-pitch-gage-4-84-tpi-51-leaf","provider":"Voomi Supply","version":"1.0","type":"link"}
