Built from high-speed steel (HSS) with a bright, uncoated finish, this tap is suited for threading operations where standard coatings are not required. It features a taper chamfer for gradual thread engagement on entry, reducing the load at the start of the cut. With 4 flutes and an H3 thread limit, it holds close dimensional tolerances appropriate for a 3B class of fit. Overall length is 3-13\/16 inches with a thread length of 1-13\/16 inches, making it a standard proportion for this thread size.\u003c\/p\u003e\u003cp\u003eThis tap is used in machine shops, maintenance operations, and manufacturing environments where left-hand 5\/8-18 UNF threaded holes are required. Left-hand taps are specified when the application demands counter-rotation resistance or where assembly design calls for reverse-thread fastening. The taper chamfer style makes this tap well suited for through-hole tapping where the tap can advance freely past the bottom of the hole. Machinists, tool and die makers, and maintenance technicians working on mechanical assemblies are the primary users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand thread direction for reverse-thread applications\u003c\/li\u003e\n\u003cli\u003eTaper chamfer provides gradual entry and reduced starting load\u003c\/li\u003e\n\u003cli\u003e4 flutes with H3 thread limit for consistent 3B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect thread form accuracy\u003c\/li\u003e\n\u003cli\u003eStandard tap proportions suitable for use in manual and machine tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production tap for any application requiring a left-hand 5\/8-18 UNF internal thread with a 3B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a tap wrench, tapping head, or CNC tapping attachment appropriate for its shank size. Secure the workpiece before tapping and ensure the pilot hole diameter is correct for 5\/8-18 UNF thread engagement. Apply cutting fluid appropriate for the workpiece material to extend tap life and improve thread finish. Because this is a left-hand tap, rotation direction must be reversed from standard right-hand tapping procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\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\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-13\/16 inches\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-04916201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716028563762,"sku":"MSC-04916201","price":53.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72b601b1971ffbd53c02b660be65978e.jpg?v=1788521242","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04916201-straight-flute-tap-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
