What size socket is a 2008 Honda Civic lug nut?
The lug nuts on a 2008 Honda Civic typically require a 19 mm (3/4 inch) socket.
Socket and fastener specifications
Important details about the lug nuts and studs you’ll encounter when servicing a 2008 Civic wheels:
- Socket size: 19 mm (3/4 inch) hex to fit the lug nuts
- Stud size and thread pitch: M12 x 1.5 (12 mm diameter with 1.5 mm thread pitch)
- Lug nut seat type: 60-degree conical seat commonly used on OEM Honda wheels
- Thread compatibility: Designed for standard OEM lug nuts that fit 12x1.5 studs
These specifications cover the typical configuration for a 2008 Civic and are consistent across most trims. If you have aftermarket wheels, verify seat type and nut dimensions to avoid misfitments.
Seat type and compatibility
Most OEM and many aftermarket wheels for the 2008 Civic use a 60-degree conical seat. If your wheels have a different seat style (for example, a ball seat), you may need different lug nuts and a different socket size. Always confirm the wheel’s hardware before driving with new fasteners.
Torque and installation procedure
Correct torque and proper technique are crucial to safety and wheel longevity. Use a torque wrench and follow a star-pattern sequence to evenly tighten lug nuts.
To guide the process, use the steps below.
- Loosen the lug nuts slightly before jacking up the car to relieve tension while the wheel is still on the ground.
- Jack up the vehicle and secure it with jack stands, then remove the wheel.
- Clean the hub surface and inspect the lug studs for damage or corrosion.
- Hand-tighten the lug nuts in a star pattern to ensure even seating.
- Torque the lug nuts to approximately 80 ft-lb (108–110 Nm) in a star pattern, rechecking that all nuts are snug and evenly tightened.
- Lower the vehicle and perform a final torque check after a short test drive to account for settling.
Following these steps helps prevent rotor warping, uneven seating, and potential wheel loosening while driving.
Periodic checks
Even after installation, periodically re-check lug nut torque—especially after the first 50–100 miles of driving or after heavy road conditions—to ensure the nuts remain properly torqued.
Summary
For a 2008 Honda Civic, the standard lug nut socket size is 19 mm (3/4 inch). The studs are M12 x 1.5 with 60-degree conical seats, and typical wheel lug torque is about 80 ft-lb (108–110 Nm). Use a torque wrench and a proper star-pattern sequence when installing or removing wheels, and verify specifications if you’re using aftermarket wheels or lug nuts.
What size are the lug nuts on a 2008 Honda Civic?
The 2008 Honda Civic uses M12 x 1.5 lug nuts. This means the lug nuts have a metric thread diameter of 12mm and a pitch of 1.5mm.
- Thread Size: M12 x 1.5
- Thread Diameter: 12mm
- Pitch: 1.5mm
Is 7/8 socket the same as 22mm?
No, a 7/8 socket is not exactly the same as a 22mm socket, but they are often used interchangeably because the difference is very small. A 7/8 inch socket is equal to 0.8750.8750.875 inches, while a 22mm socket is equal to approximately 0.8660.8660.866 inches, making the 7/8 socket slightly larger. Using a 7/8 socket on a 22mm fastener may feel a bit loose, and a 22mm socket on a 7/8 fastener may be a bit snug.
Size comparison
- 7/8 inch socket: 0.8750.8750.875 inches
- 22mm socket: 0.8660.8660.866 inches
Interchangeability and potential issues
- Using a 7/8" socket on a 22mm fastener: This may feel slightly loose because the socket is larger than the fastener.
- Using a 22mm socket on a 7/8" fastener: This may be a snug fit, which is generally better than a loose fit, but could be difficult to use.
- Recommendation: For the most precise fit, it's best to use the correct tool for the job. If you have a 22mm fastener, use a 22mm socket. If you have a 7/8 inch fastener, use a 7/8 inch socket.
When to be cautious
- Corroded or worn fasteners: If a fastener is corroded or the chrome cap has swelled, either socket may fit poorly.
- Torque: For high-torque applications, using the correct size socket is important to prevent damage to the tool or the fastener.
What size socket for Honda Civic lug nuts?
A 19mm socket is the correct size for most Honda Civics, covering models from roughly 1972 to 2025. Some specific models or aftermarket wheels may use a 17mm or 21mm socket, so it's best to check your owner's manual or confirm with the wheel and lug nut manufacturer before you start.
- Most common size: 19mm for most Honda Civic models.
- Consider other sizes: Some vehicles and aftermarket wheels may use other sizes like 17mm or 21mm, so check before assuming.
- What to use: A 6-point socket is recommended for the best grip to avoid rounding the lug nuts.
- For the best fit: Consider a socket with a thin wall for a snugger fit if you are working with a lot of clearance.
- When in doubt: Always check your owner's manual or your vehicle's specifications to be certain of the correct lug nut size.
Is 13/16 the same as 21mm?
No, 13/1613 / 1613/16 inch is not the same as $21$mm, but they are very close and often used interchangeably.13/1613 / 1613/16 inch is equal to $20.65$mm, while $21$mm is equal to approximately 0.830.830.83 inches, meaning $21$mm is slightly larger. Because the sizes are so close, a $21$mm socket or wrench will often fit a 13/1613 / 1613/16 inch nut or bolt, and vice versa, though there can be a less-than-perfect fit depending on the manufacturing tolerances of the tools and fasteners.
- 13/1613 / 1613/16 inch = $20.65$mm
- $21$mm = 0.826770.826770.82677 inches, which is slightly larger than 13/1613 / 1613/16 inch
