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 loosening due to vibration, thermal expansion, or stress. Under-torquing can lead to parts separating, rattling, or leaking. Over-torquing can damage threads, strip bolts, or deform panels leading to costly repairs. Proper torque also maintains the structural integrity of the vehicle's body.
Q2 What happens if I over-torque a body bolt?
What happens if I over-torque a body bolt?
Over-torquing can stretch or weaken the bolt, potentially causing it to fail later. It can also damage the threads in the body or the mating part, making it difficult or impossible to achieve proper torque in the future. Additionally, it can deform panels around the bolt location, leading to misalignment and cosmetic issues. For example, over-tightening a fender bolt could cause the fender to buckle.
Q3 Can I reuse body bolts?
Can I reuse body bolts?
Generally, it's recommended to replace bolts that have been subjected to high stress or torque, especially if they're torque-to-yield (TTY) bolts. For standard body bolts, inspect for damage (stripped threads, rust, or damage to the head). If they appear undamaged, reusing them with the correct torque is often okay, but it's always best practice to replace critical bolts to guarantee proper fastening. When in doubt, replace them.
Q4 Do I need to use thread locker on body bolts?
Do I need to use thread locker on body bolts?
Generally, thread locker is not required on most body bolts as the correct torque specification will provide sufficient clamping force. However, if a particular bolt is known to loosen due to vibration (such as on door hinges or panels near the engine), a low-strength thread locker can be used as an additional measure. Check your service manual for specific recommendations. Always use a low-strength variety, never high-strength, on body panels.
Q5 What tools do I need to properly torque body bolts?
What tools do I need to properly torque body bolts?
You'll need a torque wrench that covers the required torque range for the bolts you are working with, sockets that match the bolt head size, and possibly an extension or universal joint to reach difficult-to-access locations. A good quality torque wrench is crucial for accurate torque application. Calibration of torque wrenches on a regular basis is critical. Using an impact wrench is never recommended for final torque tightening.
