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 it important to use the correct torque specifications for body bolts?
Why is it important to use the correct torque specifications for body bolts?
Using the correct torque ensures that body panels are securely fastened without being over-tightened, which can damage threads, distort panels, or cause stress fractures. Under-torqued bolts can lead to panels becoming loose, causing rattles, misalignments, and potential safety issues. Proper torque values provide the optimal clamping force, maintaining structural integrity.
Q2 What happens if I overtighten a body bolt?
What happens if I overtighten a body bolt?
Overtightening a body bolt can cause several issues. It can strip the threads in the bolt or the receiving hole, requiring repair. It can also distort the body panels, leading to fitment problems or paint damage. In extreme cases, overtightening can cause the bolt to shear, creating a safety hazard and requiring extraction of the broken bolt.
Q3 Can I use a regular wrench instead of a torque wrench for body bolts?
Can I use a regular wrench instead of a torque wrench for body bolts?
While a regular wrench can be used to initially tighten a bolt, a torque wrench is crucial for final tightening to ensure the correct torque specification is met. Using only a regular wrench risks either overtightening or undertightening the bolt, both of which can lead to the problems described above. A torque wrench provides accurate and consistent results.
Q4 Should I replace body bolts when removing and reinstalling body panels?
Should I replace body bolts when removing and reinstalling body panels?
While not always strictly necessary, it is generally recommended to replace body bolts, especially self-tapping or self-locking types, whenever they are removed. Over time, threads can become fatigued, and the locking mechanisms may lose their effectiveness. Using new bolts ensures a reliable and secure connection. Always inspect bolts for damage before reuse.
Q5 What are common signs of a loose or improperly tightened body bolt?
What are common signs of a loose or improperly tightened body bolt?
Common signs include rattles or squeaks coming from the body, misaligned panels with inconsistent gaps, or in severe cases, visible movement of panels when pressing on them. In addition, you may see visible rust staining if water is allowed into the gap due to improper sealing.
