It features a large end diameter of 0.248 inches, a neck diameter of 0.198 inches, and a pin length of 1.25 inches. The 1\/4-28 threaded end accepts a nut to secure the pin against pullout, making it suitable for precision alignment and retention of assemblies subject to vibration or axial loads. Machinists, maintenance technicians, and mechanical assemblers install this fastener where repeatable, removable alignment is required in shaft-to-hub or component-to-component connections.\u003c\/p\u003e\u003cp\u003eThis threaded taper pin is used in light to medium-duty mechanical assemblies across industrial, aerospace, and general manufacturing applications. The 1\/4-28 thread conforms to AN386 standards, making it a recognized fastener type in aerospace and military maintenance environments. It is suited for manual assembly work where controlled disassembly and repositioning of mating components is part of the service procedure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSize 4 taper pin with 0.248 inch large end diameter for precise hole fitment\u003c\/li\u003e\n\u003cli\u003e1\/4-28 threaded end for positive nut retention and pullout resistance\u003c\/li\u003e\n\u003cli\u003eC-12L14 free-machining steel for consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eUncoated finish compatible with post-installation plating or treatment if required\u003c\/li\u003e\n\u003cli\u003eMeets AN386 standard for use in aerospace and military maintenance applications\u003c\/li\u003e\n\u003cli\u003eMaximum diameter tolerance of 0.0013 inches for controlled interference fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AN386-compliant Size 4 threaded taper pin for use in any application requiring a 1\/4-28 threaded taper pin with a 0.248 inch large end diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinist or maintenance technician using a pin driver or press to seat the taper into a reamed taper hole; the hole must be properly reamed to the correct taper before installation. Thread the nut onto the 1\/4-28 end after seating to lock the pin in place and prevent withdrawal. Ensure all connected machinery or power sources are de-energized or locked out before servicing any assembly containing taper pins. Do not reuse a taper pin that has been driven into a worn or oversized hole, as loss of fit will compromise joint integrity.\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\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\u003ePin Length\u003c\/strong\u003e: 1.25 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\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: 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: MSC67703769X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721086697778,"sku":"MSC67703769X","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef262137dd13e0aa1d6f2e43eeb8bc89.jpg?v=1788573308","url":"https:\/\/voomisupply.com\/products\/value-collection-msc67703769x-threaded-taper-pin-size-4","provider":"Voomi Supply","version":"1.0","type":"link"}
