Each tap is machined from high-speed steel with a bright, uncoated finish and features 4 flutes for efficient chip evacuation during through-hole and blind-hole threading operations. The overall length of 5.125 inches accommodates standard tap wrench sizes, and the H4 thread limit provides the tolerance control needed for most general-purpose threaded fastener applications. Right-hand thread direction follows standard UNC convention. This set is sized for 1-inch nominal diameter threading work and is suited to machine shop, maintenance, and fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThis tap set is used wherever a 1-8 UNC internal thread must be cut or chased in a workpiece. Typical applications include threading tapped holes in structural steel, aluminum plate, cast iron, and similar materials during equipment fabrication, repair, or assembly. The 3-piece set typically includes taper, plug, and bottoming taps, covering starting, intermediate, and finishing passes in a single kit. Machinists, maintenance mechanics, pipefitters, and general fabricators working in industrial, commercial, and field-repair settings commonly reach for this size when assembling heavy fastener joints or repairing stripped threads in large-diameter bores.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread form for large-diameter standard unified coarse-thread cutting\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry promotes chip clearance and thread quality in both through and blind holes\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit designation for controlled tolerance fit in general-purpose applications\u003c\/li\u003e\n  \u003cli\u003e2.5-inch thread length provides adequate cutting depth for typical fastener hole depths\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows visual wear inspection during service life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or service tap set for any application requiring 1-8 UNC right-hand internal threads.

Always secure the workpiece before threading and apply cutting fluid appropriate to the workpiece material to extend tap life and improve thread quality. Inspect the tap and the tapped hole between passes to avoid tap breakage, particularly in blind holes. Follow applicable shop safety practices when working with cutting tools, including eye protection and proper chip disposal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5 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\u003ePieces Included\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 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: MSC-04489043\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51727097692466,"sku":"MSC-04489043","price":162.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbc86ff52c11b377415b594c37262d92.jpg?v=1788673264","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04489043-tap-set-1-8-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
