The pin features a large end diameter of 0.248 inches and a neck diameter of 0.198 inches, with a maximum diameter tolerance of 0.0013 inches for precise fitment. The threaded end is sized 1\/4-28 UNF, allowing a nut to be applied to lock the pin securely in a tapered hole. This fastener is used to secure hubs, collars, levers, and similar components to shafts in mechanical assemblies and is typically installed by machinists, millwrights, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThreaded taper pins are a standard fastening solution in industrial machinery, HVAC equipment frames, pump assemblies, and light structural connections where a removable but positive-locking pin is required. The 1\/4-28 threaded end makes extraction straightforward using a standard nut and puller setup, which is useful in applications where periodic disassembly is expected. This pin meets AN386 standards and is suited for both original equipment assembly and field replacement work where Size 4 taper pin geometry is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSize 4 taper pin geometry with 0.248 inch large end diameter\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF threaded end for nut-assisted installation and extraction\u003c\/li\u003e\n  \u003cli\u003eC-12L14 free-machining steel for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eMaximum diameter tolerance of 0.0013 inches for tight, repeatable fitment\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — compatible with field-applied lubricants or corrosion treatments as required\u003c\/li\u003e\n  \u003cli\u003eMeets AN386 standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AN386 Size 4 threaded taper pin for use in any mechanical assembly or equipment that calls out a Size 4 taper pin hole with a 1\/4-28 threaded extraction feature.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a taper pin reamer to prepare or verify the mating hole before driving the pin. De-energize and lock out all equipment before installing or removing taper pins from rotating assemblies. Apply a nut to the threaded end and tighten to seat the pin fully; use the same nut against a spacer or puller plate for removal. Follow applicable machinery safety standards and the equipment manufacturer's torque and assembly procedures.\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\u003eLarge End Diameter\u003c\/strong\u003e: 0.248 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 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Length\u003c\/strong\u003e: 1 inch\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\u003eSurface Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: AN386\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163205\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: MSC67703728X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708525183282,"sku":"MSC67703728X","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/396b075632d967a840b16ad028ecb1b8.jpg?v=1788446828","url":"https:\/\/voomisupply.com\/products\/value-collection-msc67703728x-threaded-taper-pin-size-4","provider":"Voomi Supply","version":"1.0","type":"link"}
