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.
Can I use 7/8 socket for 22mm?
Yes, you can use a 7/8" socket for a 22mm bolt or nut because they are the same size, with a very small difference that is negligible in practice. 22mm is equal to approximately 0.8660.8660.866 inches, and 7/87 / 87/8 inch is equal to 0.8750.8750.875 inches.
- Size conversion: The two sizes are effectively interchangeable, as they are the closest imperial and metric equivalents.
- Fit: A 7/87 / 87/8" socket will fit on a 22mm bolt. It may feel a little loose, but it will still work.
- Impact tools: This combination is commonly used for impact tools, like those for lug nuts, where sockets are often stamped with both sizes.
- Warning: It's important to use a socket with the correct number of points (e.g., 6-point or 12-point) to avoid damaging the bolt or nut, especially on older or rounded-off fasteners.
