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 is using the correct torque important for body bolts?
Why is using the correct torque important for body bolts?
Proper torque ensures the body panels are securely fastened without being over-tightened, which can damage threads or distort panels. Under-tightening can cause panels to vibrate loose or shift, leading to rattles, misalignment, or potential safety hazards. For example, if a fender bolt is under-torqued, the fender could vibrate and possibly cause paint damage or detach entirely over time.
Q2 Can I reuse body bolts after removing them?
Can I reuse body bolts after removing them?
While many body bolts can be reused if they are in good condition (no rust or damage), it's generally recommended to replace self-tapping or self-locking bolts, especially if they have been removed multiple times. These types of bolts can lose their locking or thread-forming effectiveness after repeated use. Bolts used in areas such as crash structures are almost always a replacement item.
Q3 What tools do I need to tighten body bolts to the correct torque?
What tools do I need to tighten body bolts to the correct torque?
You'll need a torque wrench calibrated within the required torque range (typically inch-pounds or foot-pounds depending on the specific bolt), appropriate sockets for the bolt heads, and possibly extensions to reach certain areas. Some areas may also require a crowfoot wrench attachment for the torque wrench if the socket cannot directly fit. Having a torque adapter is also helpful for getting into tight spots.
Q4 What do I do if I accidentally over-tighten a body bolt?
What do I do if I accidentally over-tighten a body bolt?
If you over-tighten a bolt, you risk damaging the threads or the panel itself. Immediately stop tightening. If you suspect damage, remove the bolt and inspect both the bolt and the receiving threads for any stripping or deformation. If the bolt or threads are damaged, they must be repaired or replaced before reusing. Sometimes a thread chase may fix stripped receiving threads but the bolt may need to be replaced.
Q5 Are the torque specs for all body bolts the same on my 2001-2006 Acura MDX?
Are the torque specs for all body bolts the same on my 2001-2006 Acura MDX?
No, torque specifications vary depending on the bolt size and material, as well as the specific location on the body. For example, a bumper support bolt will have a different torque spec than a fender bolt. Always refer to the vehicle’s service manual for accurate specifications for each individual bolt. Never assume they are all the same.
Environmental Considerations
Temperature, humidity, and seasonal effects on torque specifications
Temperature Effects
