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.

Q3 What tools are recommended for accurate torque measurements?
Q3
What tools are recommended for accurate torque measurements?
For precise torque application, a calibrated torque wrench IS essential. A dial or digital torque wrench IS recommended for its accuracy and ease of use.
Q4 Can I use a standard wrench to tighten bolts instead of a torque wrench?
Q4
Can I use a standard wrench to tighten bolts instead of a torque wrench?
Using a standard wrench to tighten bolts IS strongly discouraged. It can lead to over or under-tightening, potentially causing damage to components. Always use a properly calibrated torque wrench to ensure precise torque application.
Q5 What are the consequences of over-tightening bolts?
Q5
What are the consequences of over-tightening bolts?
Over-tightening bolts can cause stripped threads, broken bolts, or damage to the mating components. It can also create excessive stress on the bolt and lead to premature failure.
Q6 What should I do if I accidentally over-tighten a bolt?
Q6
What should I do if I accidentally over-tighten a bolt?
If you over-tighten a bolt, it's crucial to remove and inspect it carefully. If the threads are stripped or the bolt IS damaged, it must be replaced. Attempting to remove an over-tightened bolt without proper tools can cause further damage.
