It features a small end diameter of 0.4088 inches and a large end diameter of 0.492 inches, with an overall length of 4 inches. The pin is made from C-12L14 free-machining steel, which provides consistent dimensional accuracy and reliable shear performance in mechanical assemblies. Diameter tolerance runs from -0.0007 inches to +0.0013 inches, meeting standard precision requirements for taper pin applications. Machinists, maintenance technicians, and mechanical assemblers install this type of pin to secure hubs, collars, and levers to shafts in a wide range of industrial and commercial equipment.\u003c\/p\u003e\n\u003cp\u003eThis taper pin is suited for use in mechanical drive assemblies, machine tool components, and general industrial equipment where a reliable, removable shaft-to-hub connection is needed. The self-locking taper geometry holds the pin firmly under load without threads or adhesives, making it appropriate for both new assembly and repair work. It fits standard Size 8 taper pin holes reamed to ANSI\/ASME B18.8.2 specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSize 8 taper pin conforming to ANSI\/ASME B18.8.2 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eC-12L14 free-machining steel construction for consistent accuracy and machinability\u003c\/li\u003e\n  \u003cli\u003eSmall end diameter of 0.4088 inches and large end diameter of 0.492 inches\u003c\/li\u003e\n  \u003cli\u003eOverall length of 4 inches\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance range of -0.0007 inches to +0.0013 inches\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for standard industrial environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation taper pin for standard Size 8 taper pin bores reamed to ANSI\/ASME B18.8.2 specifications in mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTaper pins are installed by machinists or mechanical maintenance technicians using a standard taper pin reamer to prepare the bore before driving the pin. Always ensure the mating bore is properly reamed to the correct Size 8 taper before installation. De-energize and lockout\/tagout all equipment before working on rotating or power-transmission components. Remove taper pins by driving from the small end using a suitable punch and hammer; do not use excessive force that may distort the bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.4088 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.492 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Diameter Tolerance\u003c\/strong\u003e: -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter Tolerance\u003c\/strong\u003e: +0.0013 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C-12L14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\/ASME B18.8.2\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: -34859-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716383539506,"sku":"-34859-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07fdc2126d875ad3e62274dba1e9db07.jpg?v=1788525239","url":"https:\/\/voomisupply.com\/products\/value-collection-34859-5-taper-pin-size-8-4-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
