The pin measures 1 inch in overall length with a small end diameter of 0.2292 inches and a large end diameter of 0.25 inches, conforming to ANSI\/ASME B18.8.2 dimensional standards. Diameter tolerances are held to -0.0007 inches on the low end and +0.0013 inches on the high end, delivering the consistent fit required for repeatable alignment in production and maintenance applications. Machinists, millwrights, and maintenance technicians use these pins to secure rotating or sliding components in place.\u003c\/p\u003e\u003cp\u003eThis taper pin is suited for light-to-medium duty mechanical assemblies where a self-locking taper fit is needed to resist axial movement and rotational load. Common install scenarios include shaft-to-hub connections, gear and pulley retention, and fixture alignment in both OEM manufacturing and field repair environments. The C-12L14 free-machining steel grade makes installation and removal straightforward in standard drill-and-ream applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI\/ASME B18.8.2 compliant dimensions for drop-in replacement in standard taper-reamed holes\u003c\/li\u003e\n\u003cli\u003eC-12L14 free-machining steel grade for ease of driving and removal\u003c\/li\u003e\n\u003cli\u003eSmall end diameter of 0.2292 inches, large end diameter of 0.25 inches\u003c\/li\u003e\n\u003cli\u003e1 inch overall length suits compact shaft and collar assemblies\u003c\/li\u003e\n\u003cli\u003eUncoated finish with controlled diameter tolerances for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Size 4 taper pin replacement for mechanical assemblies requiring ANSI\/ASME B18.8.2 compliant taper pins with a 1 inch overall length and 0.25 inch large end diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTaper pins are typically installed by a machinist or millwright using a taper reamer to prepare the mating hole before driving the pin with a hammer and pin punch. Ensure the assembly is secured and de-energized or de-loaded before installing or removing taper pins. Use the correct Size 4 taper reamer to achieve proper fit — forcing an oversized or undersized pin can split the hub or prevent proper seating. Removal is performed by driving the small end out from the large end side.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.2292 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 34840X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717375164722,"sku":"34840X","price":6813.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7768a5c97701ca7601475724155c2eaf.jpg?v=1788539364","url":"https:\/\/voomisupply.com\/products\/value-collection-34840x-taper-pin-size-4-1-in-oal-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
