9/16"-18 Lug Nuts
All of our 9/16"-18 lug nuts: 9/16 inch thread diameter with 18 threads per inch, including dualie nuts with washers for dually wheels. Stocked in acorn, bulge acorn, spline, spike and mag styles.
This size is commonly found on older Dodge Ram heavy-duty trucks, Ford F-250 and F-350 pickups from roughly 1988 to 1998 (before the Super Duty era) and many trailer axles, especially dually applications. Always verify your thread size before ordering. If you are not certain of your size, our wheel fitment guide explains how to identify thread sizes step by step.
