Thread Pitch: 14x1.5 / M14x1.5 / 14mm x 1.5. Bulge Acorn Lug Nuts XL. These lug nuts will not work with Ford OEM Factory wheels that use a washer style lug nut. We will be happy to help! Lug nuts have two compatibilities, one to match the lug nut thread size to the vehicle's wheel studs and the other to match the lug nut style to the wheel.
