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 specification for body bolts important?
Why is using the correct torque specification for body bolts important?
Using the correct torque ensures proper clamping force, preventing bolts from loosening due to vibration or stress, which can lead to rattles, misalignment, or even component failure. Over-tightening can damage the bolt or surrounding material, and under-tightening can allow components to shift. For example, an improperly torqued fender bolt could lead to a fender panel vibrating loose and creating noise.
Q2 What type of lubricant should I use on body bolts?
What type of lubricant should I use on body bolts?
Unless the manufacturer specifically states otherwise, it is generally recommended to install body bolts dry. Lubricant can change the friction and result in an inaccurate torque reading and over-tightening even when using a torque wrench. When the manual specifies lubricant, apply it sparingly on the bolt threads only; never on the bolt head or the mating surface of the component.
Q3 Do I need to replace body bolts after removing them?
Do I need to replace body bolts after removing them?
It's generally advisable to replace any torque-to-yield (TTY) bolts, which are designed to stretch upon tightening. TTY bolts are often used in critical areas and should not be reused. If not TTY, you can sometimes reuse bolts if they are in good condition. Check the threads for damage and discard any that are damaged, stretched, or corroded. A bolt with even a slight amount of visible thread deformation will not properly apply the appropriate torque.
Q4 What tools do I need for tightening body bolts to the correct torque?
What tools do I need for tightening body bolts to the correct torque?
You'll need a torque wrench, sockets that fit the specific bolt heads, and possibly extensions or adapters to reach tight spaces. A quality torque wrench is essential for accuracy. If bolts have unusual shapes (e.g., Torx) you'll need the right corresponding sockets or bits. For example, you would need a socket set including sizes commonly used on body bolts, as well as a suitable torque wrench with a range that covers the necessary torque specifications.
Q5 What should I do if I have trouble accessing a body bolt?
What should I do if I have trouble accessing a body bolt?
If you're having trouble accessing a bolt, use appropriate extensions, wobble extensions, or universal joints with your torque wrench. Ensure that the extension is rated for use with a torque wrench to avoid introducing errors into the reading. If you have an excessively difficult time reaching a particular bolt, it may be necessary to remove surrounding components to provide access.
