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 recommended torque for electrical bolts in a 2007-2012 Hyundai Veracruz?
What is the recommended torque for electrical bolts in a 2007-2012 Hyundai Veracruz?
The recommended torque for electrical bolts, such as those securing the battery terminals or grounding points, is typically between 5-7 Nm (44-62 in-lbs). Always refer to the vehicle's service manual for specific torque values, as over-tightening can damage components and under-tightening can lead to poor electrical connections.
Q2 How often should I check the torque on electrical bolts?
How often should I check the torque on electrical bolts?
It is recommended to check the torque on electrical bolts during routine maintenance, such as oil changes or tire rotations, or whenever you notice electrical issues like flickering lights or poor battery performance. Loose bolts can cause intermittent electrical connections, leading to system failures.
Q3 Can I use a regular wrench instead of a torque wrench for electrical bolts?
Can I use a regular wrench instead of a torque wrench for electrical bolts?
While a regular wrench can be used, it is not recommended. A torque wrench ensures precise tightening, which is critical for electrical components. Over-tightening can strip threads or crack components, while under-tightening can lead to loose connections and potential electrical arcing.
