What size socket is a 2012 Impala lug nut?
The lug nuts on a 2012 Chevrolet Impala typically require a 19mm (3/4 inch) socket to remove or tighten. This size matches the common M14x1.5 wheel studs used on the car’s five-lug setup.
Socket size and wheel specs
Understanding the wheel specifications helps confirm the correct tool and torque for maintenance on the Impala.
- Bolt pattern: 5 x 115 mm
- Center bore: 63.4 mm
- Lug nut type: conical-seat (acorn) nut
- Lug nut size (socket): 19 mm
Using the correct socket and seating minimizes the risk of damaging the lug nuts or studs and ensures you can apply torque evenly.
Seat type and compatibility
Most OEM and aftermarket wheels for the 2012 Impala use conical-seat lug nuts with a 19 mm (3/4 in) across-flats socket. If your wheels use a different seat (e.g., ball-seat) or a different lug-nut size, verify with the wheel manufacturer or the service manual before applying a tool.
How to verify socket size and safely service your wheels
When you're preparing to work on the wheels, follow these steps to ensure you use the right tools and stay safe.
- Park on a level surface, engage the parking brake, and place wheel chocks on the opposite wheels.
- Loosen the lug nuts slightly while the wheel is still on the ground to prevent the wheel from spinning.
- Jack up the car at the proper jacking point and secure it with jack stands.
- Remove the lug nuts in a star pattern and take off the wheel.
- When reinstalling, hand-tighten the lug nuts first, then snug them in a star pattern before torqueing to spec.
In summary, follow these steps and torque recommendations to ensure safe and secure wheel installation.
For the 2012 Impala, the typical torque specification is around 140 ft-lbs (190 N·m). Always consult the owner's manual or a dealer for the exact figure for your vehicle and wheel setup and re-torque after driving a short distance to ensure even clamping.
Summary
For a 2012 Chevrolet Impala, you will generally need a 19 mm socket to remove or install lug nuts, thanks to its standard M14x1.5 lug studs and 5x115 mm bolt pattern. The lug nuts are typically conical-seat, and always verify seat type and center bore when using aftermarket wheels. Following the correct procedure and torque specifications ensures safe wheel installation and road readiness.
What size socket fits Chevy lug nuts?
The most common Chevy lug nut socket size is 22mm (or 7/8"), especially for models like the Silverado 1500, Suburban, Tahoe, and Colorado. However, not all Chevy vehicles use the same size, as some may use 13/16", 1/2" (12.7mm), or other common sizes depending on the model and year.
Common socket sizes
- 22mm (7/8"): This is the most frequent size for many light-duty trucks and SUVs, including the Silverado 1500 and Suburban.
- 13/16": This is an equivalent size to 22mm and is often listed as the size to use.
- Other sizes: Depending on the model and year, some Chevy vehicles may use other sizes, such as 1/2" or M12 x 1.25 for smaller sedans or older models.
How to confirm the correct size
- Check your owner's manual: The manual will specify the correct lug nut socket size for your specific vehicle.
- Use a socket set with a 1/2-inch drive: This provides enough torque for most lug nuts, and a 1/2-inch drive socket allows you to tighten them with confidence.
- Try a 13/16" socket: This is an equivalent size to 22mm and is often listed as the size to use.
- Use a socket that can handle the torque: Use a high-quality socket that is designed to withstand the forces of tightening lug nuts to avoid damaging the nut or the socket.
- Avoid using cheap chrome sockets: Cheap sockets can crack or shatter under the stress of properly tightening lug nuts.
What size lug nut is on a Chevy Impala?
The Chevy Impala lug nut size varies by model year, but common sizes include M12 x 1.50 for many newer models and 7/16-20 for some older models. Always verify the specific thread size, as well as the seat style (e.g., cone, bulge acorn), length, and hex size for your particular vehicle to ensure a correct and safe fit.
| Model Year (Example) | Thread Size | Hex Size |
|---|---|---|
| 2019 | M14 x 1.50 | Varies |
| 2010 | M12 x 1.50 | 3/4" |
| 1963 | 7/16-20 | 3/4" |

What size socket do I need to take off 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
- Metric: 19mm, 21mm (most common), 17mm, 22mm
- Standard: 13/16 inch (often fits 21mm lug nuts)
How to find the right socket size
- Check your owner's manual: This is the most reliable way to confirm the correct size for your specific vehicle.
- 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.
