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 correct torque specifications important for electrical connections?
Why are correct torque specifications important for electrical connections?
Correct torque ensures proper electrical contact and prevents overheating, arcing, and potential component failure. Over-tightening can damage threads or connectors, while under-tightening can lead to high resistance and heat build-up. For example, an improperly torqued battery terminal can result in a no-start condition.
Q2 Are torque specs the same for all bolts within the electrical system?
Are torque specs the same for all bolts within the electrical system?
No, torque specifications vary greatly depending on the bolt size, material, and the components they connect. A larger ground cable bolt will have a higher torque spec than a small sensor connector screw. Always refer to the specific torque chart for the component you are working on.
Q3 Can I use an impact wrench for tightening electrical connections?
Can I use an impact wrench for tightening electrical connections?
No, it's strongly discouraged. Impact wrenches can easily over-tighten fasteners, damaging sensitive electrical components and creating a potentially unsafe electrical connection. Use a calibrated torque wrench for accurate tightening.
Q4 What should I do if I suspect a previously over-tightened electrical connection?
What should I do if I suspect a previously over-tightened electrical connection?
Visually inspect for damage such as stretched or stripped threads and stress fractures on the connector. If damage is found, replace both the fastener and connector. Clean any corrosion and ensure the replacement is torqued to spec. A loose connection may cause intermittent issues and can be indicated by corrosion or burn marks near the connection.
Q5 Do electrical connections require periodic re-torquing?
Do electrical connections require periodic re-torquing?
Generally, properly torqued electrical connections don't require routine re-torquing unless specified by the manufacturer or in high-vibration environments. However, if a connection is disturbed, it should be inspected and re-torqued if necessary, particularly after any component replacement. High-vibration areas like engine bays benefit from annual inspection.
