• Description:

  This is a genuine Ford standardized service nut carrying the W520103-S403 service number, an M10 by 1.5 hex nut on the HN1 base most often cataloged as a front muffler nut. Depending on the catalog you will also see it listed against a catalytic converter, an exhaust flange or a manifold connection. Real applications that share this exact service number include the Ford Escape, Focus, Transit and Contour, and it appears on other bodies because Ford consolidates common threaded hardware under one number. An exhaust nut that is loose or missing lets the joint it clamps leak, which can present as a ticking or roaring exhaust note, a rattle from a shifting muffler or pipe, and in some cases an exhaust smell. Exhaust fasteners run through heat cycles, so a fresh nut seats more reliably than a corroded one. Because one service number is listed against several model years and configurations, confirm the exact fit for your vehicle against your VIN before ordering so the thread size matches the stud you are servicing.
