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 Why are torque specifications important for electrical connections?
Why are torque specifications important for electrical connections?
Proper torque is crucial for reliable electrical connections. Under-tightening can lead to increased resistance, overheating, and intermittent failures due to loose connections. Over-tightening can damage the connector, threads, or the component itself, resulting in compromised connections and potential short circuits. Correct torque ensures optimal contact and reduces the risk of electrical issues.
Q2 What happens if I don't have a torque wrench for tightening electrical connections?
What happens if I don't have a torque wrench for tightening electrical connections?
While a torque wrench is highly recommended for accuracy, you can achieve a 'feel' for appropriate tightness with practice. However, be extremely cautious not to overtighten. Err on the side of slightly less tight, then recheck after a short period of operation. Avoid using extreme force. It's advisable to purchase an inexpensive torque wrench for critical electrical connections. Over-tightening is a leading cause of stripped threads, broken connectors and electrical problems down the road. When in doubt, have a professional mechanic perform the work with appropriate torque tools.
Q3 Are all electrical connection torque specifications the same on my 1996-1998 Acura TL?
Are all electrical connection torque specifications the same on my 1996-1998 Acura TL?
No, torque specifications vary depending on the size and material of the fastener (bolt, nut, screw) and the components being connected. Smaller fasteners require less torque. Refer to the specific service manual or a reputable source like AllData or Chilton for accurate torque specs for individual electrical connections on your 1996-1998 Acura TL.
Q4 What should I do if I strip or damage threads when tightening an electrical connector?
What should I do if I strip or damage threads when tightening an electrical connector?
If threads are damaged, immediately stop. You may try to carefully re-tap the hole with the correct size tap. Using a thread insert such as a Helicoil may be necessary if the threads are heavily damaged. Otherwise, it is advisable to replace the damaged component or connector as soon as possible, as a compromised connection can cause major electrical malfunctions. Do not attempt to force damaged threads.
