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 Why are torque specifications important for body bolts?
Why are torque specifications important for body bolts?
Correct torque ensures proper clamping force, preventing bolts from loosening due to vibration, and avoids damage to threads or body panels. Over-tightening can strip threads or deform panels, while under-tightening can lead to parts coming loose, causing noises or safety issues. For example, a loose bumper bolt can cause the bumper to sag or fall off.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While a torque wrench is recommended for accurate tightening, you can try tightening 'hand-tight' plus a small increment if a torque wrench is unavailable in an emergency. However, this is highly discouraged for critical components. Always use a torque wrench and consult the proper specification when possible. This helps prevent issues that may cost you more in the long run.
Q3 Can I reuse body bolts?
Can I reuse body bolts?
In most cases, body bolts can be reused if they are in good condition (no rust, stripped threads, or visible damage). However, if you observe any damage, or if the manufacturer specifies one time use for a specific bolt, replace them with new ones. Consider replacing bolts that secure load-bearing parts, such as the bumper or hood hinges to ensure proper fitment, even if they appear ok.
Q4 Do I need to use thread locker on body bolts?
Do I need to use thread locker on body bolts?
Typically, thread locker is not required for most body bolts. However, for bolts that are difficult to access or located near areas with a lot of vibration (like the door hinges or core support), a low strength thread locker like Loctite 242 may be helpful to prevent loosening over time. Always refer to service manuals for bolt-specific guidance. When in doubt using a medium-strength thread locker is never a bad idea.
Environmental Considerations

Technical Service Bulletins
Corrosion Issues Around Body Bolt Locations
2007-05-15Some 2004-2008 TSX models may experience corrosion around body bolt locations due to inadequate factory sealing. This can lead to weakened attachment points.
Resolution: Inspect body bolt locations for signs of corrosion. Clean the affected areas, apply rust inhibitor, and re-seal the bolt locations with appropriate sealant during reassembly.
Bumper Cover Alignment Issues After Minor Impact
2006-11-20Minor impacts to the bumper covers may lead to alignment issues even if no significant damage is visible. Ensure proper alignment by using the correct torque on fasteners.
Resolution: Inspect the bumper mounting points and brackets for any bends or distortion. Replace any damaged components. Correct alignment issues by loosening the bolts and repositioning the bumper before retightening to specified torque.
