Manufactured to AN386 standards from C-12L14 free-machining steel, this Size 5 pin features a 0.287-inch large-end diameter, a 0.198-inch neck diameter, and a 2-inch pin length. The 1\/4-28 threaded end allows a nut to be used for positive retention, preventing the pin from backing out under vibration or load. Maximum diameter tolerance is held to 0.0013 inches for consistent fit across mating holes. Machinists, millwrights, and maintenance technicians install these pins to align or lock components on shafts, collars, and hubs.\u003c\/p\u003e\u003cp\u003eThreaded taper pins in Size 5 are used across a wide range of industrial, OEM, and MRO applications where a removable but secure locating or locking pin is required. Common installations include shaft-to-collar connections, gear hubs, lever assemblies, and machine tool fixtures. The 1\/4-28 threaded end is particularly useful in assemblies where access to the small end of the pin is limited, allowing extraction via the threaded nut rather than a punch. Suitable for both light and moderate load applications in general mechanical assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeets AN386 standard for taper pin dimensions and tolerances\u003c\/li\u003e\n\u003cli\u003eC-12L14 free-machining steel for consistent threading and dimensional accuracy\u003c\/li\u003e\n\u003cli\u003e1\/4-28 threaded end for nut retention and controlled extraction\u003c\/li\u003e\n\u003cli\u003e0.0013-inch maximum diameter tolerance for reliable fit in reamed holes\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use as-installed or with added corrosion protection\u003c\/li\u003e\n\u003cli\u003eSize 5 taper pin geometry with 0.287-inch large-end diameter and 2-inch length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and MRO replacement taper pin for mechanical assemblies requiring an AN386 Size 5 threaded taper pin with a 1\/4-28 thread form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreaded taper pins are installed by a machinist or millwright into a reamed taper hole sized to match the pin taper. Power down and de-energize all equipment before installation or removal. The mating hole should be reamed to the correct taper using a Size 5 taper pin reamer before driving the pin to ensure proper seating and full contact along the pin length. Thread the nut onto the 1\/4-28 end after installation to secure the pin against backing out.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.287 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.198 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\u003eThread Size\u003c\/strong\u003e: 1\/4-28\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: AN386\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: MSC67704080X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690309812530,"sku":"MSC67704080X","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9da3481332cd9fe6650cb473cadbbf0.jpg?v=1788268526","url":"https:\/\/voomisupply.com\/products\/value-collection-msc67704080x-taper-pin-size-5-1-4-28-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
