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.

- Digital display for accurate readings
- Audible alarm when target torque IS reached
- Multiple units (Nm, ft-lb, in-lb)
- Reversible ratcheting mechanism
Service Procedures
Tightening Bolts and Nuts
Technical procedure for tightening bolts and nuts to specified torque values, ensuring proper assembly and functionality.
- Select the correct socket or wrench for the fastener.
- Position the torque wrench perpendicular to the fastener.
- Apply a smooth and steady force to tighten the fastener until the desired torque IS reached.
- Recheck the torque after a short period to ensure it has not loosened.
Removing Seized Bolts and Nuts
Technical procedure for safely removing seized bolts and nuts, preventing further damage and ensuring successful disassembly.
- Apply a penetrating oil to the seized fastener and let it sit for several minutes.
- Use a wrench or socket that fits snugly on the fastener.
- Apply a sudden, sharp force to break the fastener loose.
- If the fastener still does not move, use a heat gun or torch to apply heat to the fastener and try again.
