It performs a different function from an ordinary flat washer or a threaded hex nut. Select the complete factory number and original retaining-point assignment before ordering.\u003c\/p\u003e\u003ch3\u003eFunction at the heat shield\u003c\/h3\u003e\u003cp\u003eThe retaining washer secures the assigned shield attachment on its original mounting post. Its broad outer surface bears against the retained material while the center engages the intended post. Correct seating helps keep the shield positioned at the mounting point.\u003c\/p\u003e\u003cp\u003eHeat-shield assemblies can use several different types of clips, nuts and washers. A part that shares the same vehicle application may belong at a different point. Match this retainer to the original shield and post rather than substituting another nearby fastener.\u003c\/p\u003e\u003ch3\u003eCommon reasons to replace\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe washer is missing following exhaust or underbody service.\u003c\/li\u003e\n\u003cli\u003eThe center gripping features have been distorted during removal.\u003c\/li\u003e\n\u003cli\u003eThe washer no longer retains the shield correctly.\u003c\/li\u003e\n\u003cli\u003eThe retainer is bent, cracked or corroded.\u003c\/li\u003e\n\u003cli\u003eIncorrect fastening hardware was installed during a previous repair.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInspect the shield and its mounting post before fitting a replacement.
