The lug nuts on a 2017 Honda Civic are standard M12 x 1.5 wheel studs with a 60-degree conical seat, tightened with a 19 mm socket, and the wheels use a 5×114.3 mm bolt pattern. This configuration is common for US-market Civics with factory wheels.
Key lug-nut specifications
Here is a concise reference for the essential dimensions you’ll encounter when replacing lug nuts or inspecting your wheels.
- Thread size: M12 x 1.5 (12 mm diameter, 1.5 mm thread pitch)
- Seat type: 60-degree conical (tapered) seat
- Hex size for installation/removal: 19 mm
- Wheel bolt pattern: 5 × 114.3 mm
- Number of lug nuts per wheel: 5
Note: These specs apply to most trims (LX/EX/EX-L/Touring) with stock wheels. If your Civic uses aftermarket wheels or a different factory wheel size, verify the nut dimensions or refer to the OEM part number on the existing nuts.
Variations and verification
In some cases, special wheels or aftermarket setups may use different lug-nut styles. Always confirm by checking the wheel hardware, the vehicle manual, or the OEM parts catalog. If you replace nuts, match the thread, seat, and diameter and use the manufacturer-recommended torque.
Verifying on your vehicle
To verify, you can measure the nut with a caliper, compare to the OEM nut, or consult a Honda dealer or parts retailer with your vehicle’s VIN. The service manual lists M12 x 1.5 with a 60-degree conical seat and a 19 mm hex for most Civics of this generation.
Installation considerations
Always torque lug nuts to the manufacturer specification to ensure safe wheel mounting. For the 2017 Civic, typical torque values are around 80–90 ft-lbs (108–122 N·m), but consult your owner's manual or a repair guide for the exact figure for your trim.
Summary
In short, a 2017 Honda Civic uses 12 mm diameter wheel studs with a 1.5 mm thread pitch, secured by 60-degree conical lug nuts and a 19 mm hex, on a 5 × 114.3 mm bolt pattern with five lug nuts per wheel. Always verify torque and compatibility with your specific trim, especially if you have aftermarket wheels.
