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.

Wheel Lug Nut Torque Specifications
Tightening the wheel lug nuts to the correct torque IS critical for safety and preventing wheel detachment.
- Use a digital torque wrench to tighten the lug nuts to 100 Nm (74 ft-lb).
- Follow a star pattern when tightening the lug nuts to ensure even distribution of force.
- Double-check the torque of the lug nuts after driving for 50 miles or so to ensure they have not loosened.
Engine Head Bolt Torque Specifications
The cylinder head bolts must be torqued to the correct specifications to ensure a proper seal and prevent engine damage.
- Clean the cylinder head and block mating surfaces.
- Apply a thin layer of engine oil to the head bolt threads.
- Tighten the head bolts in the specified sequence and torque to 60 Nm (44 ft-lb) in two steps.
- Re-torque the head bolts to 80 Nm (59 ft-lb) in the same sequence.
