Built from high-speed steel (HSS) with a bright\/uncoated finish, this tap delivers reliable thread cutting in a range of metalworking and maintenance applications. The taper chamfer eases entry into the workpiece and progressively distributes cutting load across multiple teeth. With 4 flutes and an H3 thread limit, it holds dimensional accuracy for 3B class-of-fit threads. Overall length is 2-23\/32 inches with a 1 inch thread length. Licensed machinists, tool-and-die makers, and maintenance mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations in job shops, production facilities, and maintenance environments where left-hand threaded fasteners are required. Left-hand taps are commonly used to prevent loosening on rotating shafts, counterclockwise assemblies, and specialized mechanical components. The taper chamfer style makes it a first-choice tap when starting a thread from scratch in a through-hole or when a plug or bottoming tap will finish the hole. It is intended for use in a hand tap wrench, tapping fixture, or manual machine setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand thread direction for counterclockwise thread applications\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes cutting load for easier thread starting\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit maintains 3B class-of-fit dimensional tolerance\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides good chip control in a range of materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers durability across general-purpose cutting\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for standard threading operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for standard 5\/16-18 UNC straight flute taps used in general metalworking, maintenance, and manufacturing threading applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed by a qualified machinist or maintenance mechanic familiar with thread-cutting procedures. Always de-energize and lock out any powered equipment before performing tapping operations on a mounted workpiece. Use the appropriate cutting fluid for the material being tapped to extend tap life and improve thread finish. Do not force the tap; back off periodically to break chips and prevent tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-23\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\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: MSC-04911202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700965638450,"sku":"MSC-04911202","price":18.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5803b29451f64f808ec27f95dd7cc39.jpg?v=1788395982","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04911202-straight-flute-tap-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
