Built from high speed steel with a bright uncoated finish, it delivers consistent thread form in low- to moderate-volume tapping operations. The plug chamfer — 3 to 5 threads of lead — makes this tap suitable for through-holes and deeper blind holes where a starting chamfer is not required. With 4 flutes and an H4 thread limit, it holds tight tolerances for 3B class-of-fit threads. Overall length is 4-11\/16 inches. Machinists and tool-and-die professionals use this tap in manual tapping handles or low-speed drill press setups.\u003c\/p\u003e\n\u003cp\u003eThis tap is sized for 7\/8-16 Unified National Special threads, a coarser-pitch alternative to standard UNC or UNF configurations at the 7\/8 inch diameter. It is suited for repair work, prototype fabrication, and low-production threading in machine shops, maintenance environments, and industrial assembly. Right-hand thread direction is standard. The bright finish makes it a cost-effective choice where cutting fluid is applied manually and extended coating life is not a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-16 UNS thread form with plug chamfer for through-hole and deeper blind-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for use across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit holds 3B class-of-fit tolerances for precision thread engagement\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry provides consistent chip formation in hand tapping operations\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with standard cutting oils and tapping fluids\u003c\/li\u003e\n  \u003cli\u003e4-11\/16 inch overall length provides clearance in standard tap wrenches and T-handles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard manual tap wrenches and T-handle drivers sized for 7\/8-16 thread applications.

Secure the workpiece firmly before tapping and apply a suitable cutting fluid throughout the operation to reduce heat and extend tool life. Back the tap off periodically to break chips and prevent binding. Never force a tap against resistance — back out and clear chips before continuing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\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\u003eClass of Fit\u003c\/strong\u003e: 3B\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\u003eFlute Style\u003c\/strong\u003e: Straight\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\u003eOverall Length\u003c\/strong\u003e: 4-11\/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\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: JY4848099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690613735730,"sku":"JY4848099","price":125.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/624dfb3b5049c9f3a6845a7711670efe.jpg?v=1788272621","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4848099-hand-tap-7-8-16-uns-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
