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 torque specification for the body bolts on a 2008-2013 Infiniti EX35?
What is the torque specification for the body bolts on a 2008-2013 Infiniti EX35?
The torque specification for the body bolts on a 2008-2013 Infiniti EX35 is typically 45-55 ft-lbs (61-75 Nm). However, always refer to the vehicle's service manual for exact specifications, as variations may exist depending on the specific bolt location and model year.
Q2 Can I reuse body bolts after removal?
Can I reuse body bolts after removal?
It is generally not recommended to reuse body bolts, as they are often designed as torque-to-yield (TTY) bolts. These bolts stretch during installation and may lose their clamping force if reused. Always replace body bolts with new ones to ensure proper torque and safety.
Q3 What happens if I over-torque the body bolts?
What happens if I over-torque the body bolts?
Over-torquing body bolts can lead to thread damage, bolt stretching, or even component failure. This can compromise the structural integrity of the vehicle and lead to safety issues. Always use a calibrated torque wrench and follow the manufacturer's specifications.
Q4 How often should body bolts be checked for proper torque?
How often should body bolts be checked for proper torque?
Body bolts should be checked for proper torque during routine maintenance or after any significant impact or repair work. If you notice unusual noises, vibrations, or alignment issues, inspect the body bolts immediately.
