{"product_id":"cummins-30","title":"Cummins — Hex Flange Lock Nut M10 Turbo Mount — 3818824","description":"\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe Cummins 3818824 is a hexagon flange lock nut used as heavy-duty engine fastening hardware on select Cummins diesel applications. It is commonly used in high-heat mounting locations such as turbocharger-to-exhaust-manifold studs, where the fastener must maintain clamping force under exhaust temperature, vibration, and repeated heat cycling. The integral flange helps spread load at the mounting surface while the locking design helps resist loosening in severe-duty engine environments.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-spread=\"false\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eCummins part number:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 3818824\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eProduct type:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Hexagon flange lock nut\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eThread size:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e M10 x 1.5\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eNut style:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Flanged locking hex nut\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eCommon service location:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Turbocharger mounting \/ exhaust-side engine hardware\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eAcross-flats measurement:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Approximately 0.578\"\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eHeight:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Approximately 0.421\" \/ 10.7 mm\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eService environment:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e High-temperature, high-vibration diesel engine mounting locations\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eFunction:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Secures mounted engine components while distributing clamp load through the flange face\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan\u003eEngine Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThis fastener is commonly associated with select Cummins mid-range diesel engine platforms where the parts diagram calls for part number 3818824, including applications in the following families:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul data-spread=\"false\"\u003e\n\u003cli\u003e\u003cspan\u003eCummins 5.9L 6BT \/ ISB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCummins 6.7L ISB \/ QSB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCummins 6C 8.3L\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCummins ISC\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCummins ISL\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCummins QSL\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eUse only where the Cummins parts diagram, engine serial number, or service manual specifies 3818824 or a confirmed replacement number.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan\u003eSerial Number Fitment Notice\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eFastener fitment should be confirmed by engine serial number, CPL, turbocharger mounting arrangement, stud size, and parts diagram location.
