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 importance of correct electrical bolt torque?
What is the importance of correct electrical bolt torque?
Proper torque on electrical bolts ensures secure connections, preventing loose connections and potential short circuits. Incorrect torque can lead to overheating, electrical malfunctions, and even fire hazards. For example, a loose connection in a headlight wiring harness could cause intermittent dimming or complete failure of the lights, potentially leading to accidents.
Q2 How do I know if an electrical bolt is loose?
How do I know if an electrical bolt is loose?
A loose electrical bolt might exhibit signs of vibration or movement when touched. You might notice intermittent electrical issues, such as flickering lights or erratic operation of electrical components. In some cases, a loose bolt might even visibly protrude from its housing or have a noticeable gap around it.
Q3 What tools are needed for electrical bolt torque?
What tools are needed for electrical bolt torque?
A torque wrench is absolutely essential. A standard screwdriver will not provide the necessary precision and control. A torque wrench specifically designed for electrical work (often with a smaller range) is recommended. Also, insulated screwdrivers and/or pliers are necessary to handle electrical components safely.
Q4 Why are torque specifications different for different electrical components?
Why are torque specifications different for different electrical components?
Different electrical components have different current carrying capacities and structural designs. The torque needed to secure a connector for a high-current starter relay will be significantly higher than that for a low-current interior light bulb connector. The torque specifications account for the materials, the expected stresses, and the potential for vibration and movement during operation.
Environmental Considerations
Temperature, humidity, and seasonal effects on torque specifications
Temperature Effects
Includes: High Heat, Cold Weather, Thermal Cycling
Temperature Effects
