Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
Always use a calibrated torque wrench and follow specifications exactly.
Incorrect Torque Sequence
Tightening bolts in the wrong order can cause uneven pressure distribution and potential leaks or damage.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Clean and inspect all threads before assembly. Use new thread locker if specified.
Reusing TTY Bolts
Torque-to-yield bolts are designed to stretch and must not be reused.
Always replace TTY bolts with new ones. They are single-use only.
Dry vs. Lubricated
Not accounting for whether torque specs are for dry or lubricated fasteners can lead to incorrect tension.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What is the recommended torque specification for electrical bolts in the Ferrari GTC4LUSSO?
What is the recommended torque specification for electrical bolts in the Ferrari GTC4LUSSO?
The recommended torque specification for electrical bolts in the Ferrari GTC4LUSSO (2016-2021) typically ranges from 8 to 12 Nm (Newton-meters), depending on the specific component. Always refer to the official Ferrari service manual for precise values, as over-tightening can damage electrical connectors or terminals.
Q2 How often should electrical connections be checked for proper torque?
How often should electrical connections be checked for proper torque?
Electrical connections should be checked during routine maintenance or whenever electrical issues arise. For the Ferrari GTC4LUSSO, it is recommended to inspect and verify torque specifications every 12 months or 10,000 miles, whichever comes first. Loose connections can lead to electrical failures or fire hazards.
