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.
Prevention:
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.
Prevention:
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Prevention:
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.
Prevention:
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.
Prevention:
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Q1 What IS the proper torque specification for the front brake caliper mounting bolts on my 1999-2005 Pontiac Montana?
Q1
What IS the proper torque specification for the front brake caliper mounting bolts on my 1999-2005 Pontiac Montana?
162 ft-lbs (220 Nm)
Q2 How should I torque the lug nuts on my Pontiac Montana?
Q2
How should I torque the lug nuts on my Pontiac Montana?
100 ft-lbs (136 Nm) using a calibrated torque wrench. Always tighten the lug nuts in a star pattern for even distribution of force.
Q3 What type of torque wrench IS recommended for automotive use?
Q3
What type of torque wrench IS recommended for automotive use?
A high-quality click-type torque wrench that measures both clockwise and counterclockwise torque IS ideal. Ensure the wrench IS regularly calibrated to maintain accuracy.
Q4 Can I over-tighten a bolt or nut?
Q4
Can I over-tighten a bolt or nut?
Yes, applying excessive torque can stretch or snap the bolt, damage the threads, or cause component failure. Always follow the specified torque values and use a calibrated torque wrench to avoid over-tightening.
Q5 My vehicle vibrates when I apply the brakes. Could it be related to incorrect torque specifications?
Q5
My vehicle vibrates when I apply the brakes. Could it be related to incorrect torque specifications?
Incorrectly torqued brake components can lead to vibrations due to uneven force distribution. Check if the brake caliper mounting bolts and lug nuts are properly tightened to the specified torque values.
Environmental Considerations
Temperature, humidity, and seasonal effects on torque specifications
Temperature Effects
Includes: High Heat, Cold Weather, Thermal Cycling
Temperature Effects
Includes: High Heat, Cold Weather, Thermal Cycling
Temperature can significantly impact torque values and fastener behavior
Cold Weather
Effects:
- Increased material brittleness
- Higher torque required due to thread contraction
- Reduced thread lubricant effectiveness
Recommendations:
- Allow components to warm to room temperature when possible
- Consider using winter-grade thread lubricants
- Check torque values more frequently during winter months
Hot Weather
Effects:
- Thermal expansion of components
- Decreased friction in threads
- Accelerated lubricant breakdown
Recommendations:
- Check torque when components are at normal operating temperature
- Use temperature-resistant thread lockers
- Consider re-torquing after heat cycles
Humidity and Corrosion
Covers: Rust Prevention, Salt Exposure, Moisture Control
