What size socket goes on a lug nut?
The most common socket sizes for lug nuts are 19mm or 21mm, but sizes can vary by vehicle. A 13/16-inch socket is often the correct imperial size, as it's very close to 21mm. To ensure the correct fit, check your vehicle's manual, or bring a lug nut to a hardware or auto parts store to get the right size socket. A 1/2-inch drive socket wrench is recommended for its torque capacity.
Common lug nut socket sizes

How to find the right socket size

- Measure or bring a lug nut: If you don't have your manual, take one of the lug nuts to a hardware or auto parts store to find the correct socket size.
- Use a socket set: Consider getting a set of sockets specifically designed for lug nuts, which often includes both common metric and imperial sizes, like those from TEKTON Hand Tools.
Tips for removing and installing lug nuts
- Use a 6-point socket: A 6-point socket is less likely to round off the corners of the lug nut compared to a 12-point socket.
- Use a deep-wall socket: Deep-wall sockets are designed to fit over the lug nut and are often necessary when the nut is recessed within the wheel.
- Choose the right drive size: A 1/2-inch drive is recommended for lug nuts because it can handle the higher torque often required for tightening them properly.
- Use a torque wrench: Always use a torque wrench to tighten lug nuts to the manufacturer's specifications to ensure proper and safe installation.
