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 What is the torque specification for the battery terminal bolts on a 2006-2010 Dodge Charger?
What is the torque specification for the battery terminal bolts on a 2006-2010 Dodge Charger?
The battery terminal bolts should be torqued to 7-9 ft-lbs (9.5-12.2 Nm). Over-tightening can damage the terminals, while under-tightening may lead to poor electrical connections and potential starting issues.
Q2 How often should I check the torque on electrical connections?
How often should I check the torque on electrical connections?
It is recommended to check the torque on critical electrical connections, such as battery terminals and alternator bolts, every 12 months or during routine maintenance. Vibrations and temperature changes can cause bolts to loosen over time.
Q3 What happens if I over-torque the alternator mounting bolts?
What happens if I over-torque the alternator mounting bolts?
Over-torquing the alternator mounting bolts can strip the threads or crack the alternator housing, leading to costly repairs. The correct torque specification for alternator bolts is typically 18-22 ft-lbs (24.4-29.8 Nm).
Q4 Can I use a standard torque wrench for electrical components?
Can I use a standard torque wrench for electrical components?
Yes, a standard torque wrench can be used, but ensure it is calibrated and set to the correct torque range for electrical components. Using an inch-pound torque wrench is ideal for smaller bolts to avoid over-tightening.
