FAQs
Can I use this bolt with a ball-seat wheel?
No. This bolt is specifically designed for a 60-degree conical seat. Using it with a ball-seat wheel will not provide a safe or proper connection.
What is the correct torque specification?
Always refer to your vehicle's owner manual or the wheel manufacturer's torque specifications, as the required torque depends on the vehicle's hub design.
Does this bolt fit all vehicles with M12x1.75 threads?
While the thread is correct, you must also confirm that the 40mm shaft length and 60-degree seat meet the specific requirements for your wheel and hub combination.
Is this bolt intended for use with wheel spacers?
This bolt is 40mm long. If you add wheel spacers, you may need a longer bolt to maintain sufficient thread engagement. Check your total required length after accounting for spacer thickness.
What tools do I need for installation?
You will need a 19mm hex socket, a torque wrench, and a socket extension.
Troubleshooting
Bolt does not thread into the hub smoothly
Stop immediately, clean the threads on both the hub and the bolt, and check for cross-threading or incorrect thread pitch.
Bolt feels loose after being tightened
Verify that the wheel seat type (conical vs. ball) matches the bolt and ensure the shaft length is not too long, which could cause the bolt to bottom out.
Pros and Cons
Pros
- Precision-engineered for secure wheel retention
- Standardized 60-degree conical seat ensures compatibility with most aftermarket wheels
- Durable finish resistant to standard environmental corrosion
- Easy to install using common 19mm socket tools
Cons
- Specific 40mm length may not be suitable for all wheel spacers or hub types
- Incorrect seat type (conical vs ball) can damage wheels if mismatched
- Single bolt replacement requires verifying thread count and pitch of existing hardware
Setup, Compatibility & Care
To ensure safety, verify that your wheel hub requires an M12x1.75 thread pitch and that your wheels are drilled for a 60-degree conical seat. Clean the wheel hub threads and the bolt threads prior to installation to remove any debris or rust. Always tighten bolts in a star or cross pattern to ensure the wheel is seated evenly against the hub. Avoid using high-powered impact guns to tighten these bolts, as this can lead to over-torquing and potential bolt fatigue. Periodically check the torque of your lug bolts after the first 50 miles following a wheel change.
