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?
Correct torque ensures a secure and reliable electrical connection. Over-tightening can damage components, strip threads, or cause internal stress leading to failures. Under-tightening can cause loose connections, resulting in increased resistance, overheating, and intermittent circuit issues, or even arcing, which may cause fires in extreme cases. Torque specifications also contribute to consistent and predictable component performance.
Q2 What happens if I over-torque an electrical bolt?
What happens if I over-torque an electrical bolt?
Over-torquing can deform electrical terminals, damage the components being fastened, and potentially break the bolt itself. In the case of delicate electrical connectors, too much torque can damage the fragile inner elements of the connection, leading to shorts, opens or intermittent connections. It can also affect contact pressure and increase the risk of damage, heat or poor conductivity. Over-tightening can cause stripped threads which can be costly to repair.
Q3 What happens if I under-torque an electrical bolt?
What happens if I under-torque an electrical bolt?
Under-torquing an electrical bolt leads to a loose connection. This can cause increased electrical resistance, leading to overheating, voltage drops, intermittent electrical failures and possible arcing. A loose connection may cause the component to operate improperly or fail completely. For example, a loose battery terminal will experience increased resistance, voltage drop, and may not start the vehicle. It is also a safety issue if arcing occurs.
Q4 Do I need to use a torque wrench for all electrical bolts?
Do I need to use a torque wrench for all electrical bolts?
While not always critical for every tiny screw, a torque wrench is crucial for important connections like battery terminals, ground connections, starter motor terminals, alternator bolts, and any connections on the electrical power distribution circuits or when securing sensitive electronics components like relays or modules. Following torque specifications on these connections prevents future failures. For example a main power distribution lug secured at incorrect torque could lead to significant power distribution issues. Small screws in electrical connectors and smaller signal circuit bolts may not require a torque wrench, but should still be tightened to a snug fit.
Q5 What type of torque wrench should I use for electrical components?
What type of torque wrench should I use for electrical components?
A properly calibrated, beam, clicker or digital type torque wrench that measures within the range of your application is ideal. The torque wrench should be calibrated periodically to ensure accuracy. Use a low range torque wrench when tightening smaller connectors and use a mid-range torque wrench for larger bolts. In general, use an inch-pound or Newton-meter reading torque wrench appropriate for the component’s torque specification. Do not use a wrench with excessive measurement range for small low torque applications.
