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 stress. Under-torquing can lead to parts detaching, while over-torquing can damage threads or the body panel itself, potentially causing cracks or deformations. For example, an improperly torqued bumper bolt might cause the bumper to sag or detach while driving.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While it's highly recommended to use a torque wrench for precise tightening, you might be tempted to guess. Avoid this. Guessing is often inaccurate and can lead to damage. If you lack a torque wrench, borrow one, rent one, or take the car to a professional. It's a relatively affordable investment compared to repairing stripped threads or damaged panels. For example, overtightening a fender bolt by hand can crush the fender.
Q3 Can I reuse body bolts?
Can I reuse body bolts?
Generally, reusing body bolts is acceptable if they are in good condition (no stretching, damage, or corrosion). However, it's best practice to replace bolts if there's any doubt about their integrity, especially for critical connections or those that have been subjected to high stress. When reinstalling bolts that are to be reused, a light coating of anti-seize compound on the threads is beneficial, particularly if they've been exposed to the elements. Consider replacing bolts that are heavily corroded, as torque readings can be inaccurate.
Q4 Are the torque specs the same for all body bolts?
Are the torque specs the same for all body bolts?
No, torque specifications vary significantly depending on the bolt size, material, and its location on the vehicle. For instance, a bumper bolt has a different torque spec than a fender bolt. Always refer to the specific torque specification for the bolt you are working on, found in the repair manual or a reliable database. Using a torque spec from another location can result in an improper fit or damage. Don't assume all 10mm bolts are torqued the same.
Q5 What if I strip a bolt or a thread during installation?
What if I strip a bolt or a thread during installation?
If you strip a bolt or the threads in the body, don't force it. For a stripped bolt, you may have to carefully extract the broken bolt. For stripped threads, using a thread repair kit or a Heli-Coil is often necessary. Always use the correct tools and be careful. If you are not comfortable repairing stripped threads, consult a professional. For example, cross-threading a bolt on the rocker panel can require extensive repair.
