What is the thread pitch of a Dodge lug nut?
There isn’t a single thread pitch that applies to all Dodge lug nuts. The pitch varies by model, year, and wheel size. Common possibilities you may encounter include imperial 1/2-20 UNC and metric sizes such as M12x1.75 or M14x1.5, but the exact size must be verified for your specific vehicle.
Understanding lug nut thread pitch matters for proper fit and safe operation. Different Dodge models use different stud diameters and thread pitches, and even wheel accessories like spacers or aftermarket wheels can influence which lug nuts are correct. This article provides an overview and practical steps to identify the right size for your Dodge.
Why there isn’t one universal thread pitch for Dodge
Automakers use a mix of imperial and metric thread standards across different generations, markets, and vehicle lines. Dodge, like many brands, has used several lug nut thread sizes over the years depending on the platform (cars, trucks, or performance models) and wheel specs. To ensure a secure fit, you should confirm the exact pitch for your particular vehicle configuration.
Common thread pitch options you might see on Dodge vehicles
Below are typical thread sizes you may encounter on Dodge models. The actual size for your car or truck depends on the year, model, and wheel setup.
- 1/2-20 UNC (imperial) — a common size on older Dodge passenger cars and some trucks.
- M12x1.75 (metric) — frequently found on newer Dodge vehicles with 12 mm studs.
- M14x1.5 (metric) — another common metric option on certain Dodge models and wheels.
Because Dodge vehicles span many generations and markets, some configurations may use different sizes or seat types. Always verify before purchasing replacements or aftermarket parts.
How to determine the exact lug nut thread pitch for your Dodge
To identify the correct thread pitch for your lug nuts, follow these steps.
- Check the owner's manual or the vehicle’s specification sheet for lug nut size information specific to your model and year.
- Inspect the lug studs and nuts: measure the stud diameter with calipers and determine the thread pitch with a thread gauge or by counting threads per inch (imperial) or per millimeter (metric).
- If you don’t have a gauge handy, bring a sample lug nut and a caliper to a parts retailer or mechanic, who can match the correct size by inspection and fit testing.
- Confirm the seat style (conical, ball, or flat) because the seat type also affects compatibility and mounting security.
Accurate identification helps prevent cross-threading, improper seating, and unsafe mounting. When in doubt, rely on official specifications or professional assistance.
Summary
In short, Dodge lug nut thread pitch is not universal. It varies across models and generations, with imperial and metric sizes appearing in different eras. To ensure a correct fit, verify the exact size for your vehicle through the manual, OEM parts catalogs, or professional measurement, and consider the lug nut seat type as well as the wheel and stud dimensions.
What is the pitch of a Dodge lug nut?
The most common sizes of Dodge lug nuts are M14x1. 5mm/M12x1. 5mm thread pitch, 13/16″ hex, and standard size 60-degree conical seat. Aftermarket Dodge wheel nuts are various in styles, seat types, and materials.

Is 1/2 or 3/8 better for lug nuts?
Is 1/2 or 3/8 better for lug nuts? A 1/2-inch drive is better for lug nuts because it covers the torque range most vehicles require and allows you to tighten them with confidence.
What vehicles have 9 16 18 lug nuts?
9/16-18 lug nuts fit a range of Ford, Dodge, Ram, and Chevrolet/GMC vehicles, particularly older models and many of the heavier-duty trucks and SUVs from the late 1980s through the 2010s. They are also compatible with most aftermarket wheels that use a 9/16-18 thread pitch and a 60-degree conical seat. It's essential to confirm the correct thread pitch and seat type for your specific vehicle and wheels to ensure a proper and safe fit.

- Chrysler: 2006-2009 Aspen
Important considerations
- Aftermarket vs. OEM: Some lug nuts are designed for aftermarket wheels, while others are direct replacements for original equipment manufacturer (OEM) wheels. Make sure the lug nuts match the type of wheels you have.
- Thread pitch: The "9/16-18" specifies the size and thread count. The "9/16" refers to the stud diameter, and the "18" is the number of threads per inch. You must match this to your vehicle's studs.
- Seat type: The seat type (e.g., conical, spherical) must match your wheel to ensure proper contact and secure mounting.
- Confirm fitment: Always verify the exact fitment for your specific year, make, and model before purchasing.
