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 is crucial to ensure proper clamping force, preventing bolts from loosening over time due to vibration and thermal expansion. Insufficient torque can lead to components shifting, while excessive torque can damage threads or distort body panels. For example, an improperly torqued fender bolt might loosen, causing the fender to rattle or misalign.
Q2 What happens if I over-tighten a body bolt?
What happens if I over-tighten a body bolt?
Over-tightening can stretch the bolt beyond its yield strength, potentially damaging the threads in the body panel or the bolt itself. This can result in stripped threads, requiring repairs, and may even lead to bolt failure and component separation. An overtightened door hinge bolt, for example, could damage the hinge or the door frame.
Q3 What happens if I under-tighten a body bolt?
What happens if I under-tighten a body bolt?
Under-tightening a bolt provides insufficient clamping force, causing components to shift or vibrate loose. This can lead to rattles, squeaks, misalignment of body panels, and eventual component failure. An undertightened bumper bolt, for instance, might cause the bumper to sag or detach over time.
Q4 Do I need to use a torque wrench for all body bolts?
Do I need to use a torque wrench for all body bolts?
While some minor body panels can be secured with a good 'feel' for torque, using a torque wrench is always recommended, especially for critical components like door hinges, bumper supports, and frame attachments. Proper torque ensures the integrity and safety of the vehicle's structure. A torque wrench is highly recommended on anything related to structural components of the body.
Q5 Should I use thread locker on body bolts?
Should I use thread locker on body bolts?
Thread locker is not usually required for most body bolts unless specifically indicated by the manufacturer. It's important to follow the service manual recommendations for each specific application. If the manual calls for thread locker, use the specified type (e.g., blue medium strength).
