It measures 3 inches overall length, with a small end diameter of 0.1876 inches and a large end diameter of 0.25 inches. The pin is manufactured to ANSI\/ASME B18.8.2 standards, ensuring dimensional accuracy within a minimum diameter tolerance of -0.0007 inches and a maximum diameter tolerance of 0.0013 inches. Taper pins are used to secure hubs, collars, and mating components on shafts by driving the tapered body into a reamed hole, creating a tight mechanical lock without fasteners.\u003c\/p\u003e\n\u003cp\u003eThis taper pin is suited for general-purpose industrial and mechanical assembly applications where precise, removable shaft-to-hub connections are required. Typical use cases include machine tools, conveyor assemblies, gearboxes, and mechanical linkages where alignment and load transfer between a rotating shaft and a mounted component must be maintained. Installation is performed by machinists, millwrights, and maintenance mechanics working on rotating equipment and precision assemblies. The C-12L14 free-machining steel grade is well suited for environments where moderate strength and good machinability are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSize 4 taper pin per ANSI\/ASME B18.8.2 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eC-12L14 free-machining carbon steel for good machinability and consistent tolerance control\u003c\/li\u003e\n  \u003cli\u003eSmall end diameter of 0.1876 inches, large end diameter of 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e3 inches overall length suitable for standard hub and collar applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no coating thickness to account for in critical bore fits\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance range (-0.0007 inches to +0.0013 inches) for reliable press fit in reamed holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI\/ASME B18.8.2-compliant Size 4 taper pin for use in standard tapered-hole applications requiring a 3-inch OAL pin with a 0.25-inch large end diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTaper pins are installed by machinists and millwrights using a taper pin reamer to prepare a correctly sized hole, followed by driving the pin with a hammer or press until seated. Always de-energize and lock out rotating equipment before servicing shaft-mounted components. Remove taper pins by driving from the small end using a pin punch of appropriate diameter. Do not reuse a taper pin that shows deformation, galling, or wear at the contact surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.1876 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.25 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: 34844X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716061004082,"sku":"34844X","price":1302.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b1f1d13e52ec1104a66f4b38a8fd8c3.jpg?v=1788521780","url":"https:\/\/voomisupply.com\/products\/value-collection-34844x-taper-pin-size-4-3in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
