What size are the lug nuts on a Chevy Cobalt SS?
The stock lug nuts on a Chevy Cobalt SS are 14 mm in hex size, used with a 5x110 bolt pattern, and they are typically torqued to about 100 ft-lb. This answer reflects the factory setup and common configurations for wheels designed for the Cobalt SS, but aftermarket wheels can differ.
The Chevy Cobalt SS sits in the late-2000s GM lineup as a compact performance model. While the standard hardware is consistent for factory wheels, variations can occur with different wheel packages or aftermarket replacements. This article reviews the typical stock specs and provides guidance for confirming your exact setup.
Stock lug nut specifications for the Cobalt SS
Below are the specifications you’re most likely to encounter on stock wheels or wheels designed specifically for the Cobalt SS’s bolt pattern. Use this as a baseline, but verify for any aftermarket configuration.
- Socket size (hex): 14 mm
- Bolt pattern: 5x110 mm
- Seat type: 60-degree conical (common on GM wheels)
- Torque specification for lug nuts: about 100 ft-lb (135 N·m)
- Wheel compatibility: Works with stock wheels and many aftermarket wheels designed for 5x110; verify with the wheel manufacturer if necessary
These specifications provide a solid baseline for the factory setup and for many wheels designed to fit the Cobalt SS. If your wheels or hardware differ, the lug nut size, seating, or torque may vary.
How to verify the exact lug nut size on your wheels
To ensure you have the correct hardware for your specific configuration, follow these steps to confirm lug nut size and compatibility.
- Consult the owner's manual or GM service manual for the official lug nut size, thread pitch, and torque specification for your model year.
- Inspect your current lug nuts or wheel documentation for any stamped size, seating, or part numbers that indicate the hex size.
- Measure the lug nut hex across flats with a caliper or ruler, or try fitting an appropriately sized socket (start with 14 mm) to verify the correct size without forcing.
- If you have aftermarket wheels, check the wheel manufacturer’s documentation or contact the installer to confirm lug nut requirements (hex size, thread pitch, and seat type).
- Always tighten lug nuts to the recommended torque and ensure proper seating to avoid damage or unsafe installation.
Verifying these details helps prevent cross-threading, under- or over-tightening, and ensures safe driving with your chosen wheels.
Summary
For most Chevy Cobalt SS models, the stock lug nuts are 14 mm in hex size, fit a 5x110 bolt pattern, and require about 100 ft-lb of torque. Always confirm with your specific wheels and consult the owner’s or service manual if you’re using aftermarket hardware to ensure proper fit and safety.
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 size socket does a Chevy lug nut take?
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.
