Built from high speed steel (HSS) with a bright, uncoated finish, this tap features a plug chamfer and two flutes configured to push chips forward ahead of the cutting edge, making it well-suited for production threading in open-ended holes. The 1\/4-28 UNF thread profile delivers fine-pitch threads with a 1 inch thread length. The H3 thread limit provides a controlled tolerance for consistent 3B class of fit results across repeated use. Installed by machinists, tool-and-die workers, and maintenance technicians in shop and field environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for threading 1\/4-28 UNF fine-thread holes in through-hole workpieces made of steel, aluminum, and similar machinable materials. The spiral point geometry works most efficiently in materials where chip evacuation forward through the hole is possible. It is a right-hand tap driven by standard tap wrenches, machine tap holders, or CNC tapping attachments. Typical applications include fabrication shops, maintenance and repair operations, and light manufacturing where fine-thread fastener holes are required in metal components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine-thread profile with 1 inch thread length\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of machinable metals\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent 3B class of fit tolerance\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; compatible with standard tapping drives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for 1\/4-28 UNF through-hole tapping operations requiring a 3B class of fit with an H3 thread limit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eUse appropriate cutting fluid or tapping compound for the workpiece material to reduce friction and extend tap life. Ensure the tap is aligned perpendicular to the workpiece surface before applying torque to avoid tap breakage or off-axis threads. Power down or disengage tapping equipment before changing or inspecting the tap. Follow applicable shop safety and machine guarding procedures when operating tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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-04540282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693088702770,"sku":"MSC-04540282","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5b349188546ef13a9b93720086a2e33.jpg?v=1788307170","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04540282-spiral-point-tap-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
