Importance of Using Threadlocker on Starter Bolts
Threadlocker is a type of adhesive used to secure bolts, screws, and other threaded fasteners. It is designed to ensure that the fasteners do not loosen or come apart due to vibration, temperature changes, or other factors. When it comes to starter bolts, using threadlocker is crucial for several reasons.
- Prevents Vibrations – Starter bolts can come loose due to the vibrations produced by the engine. These vibrations can cause the bolts to become loose, which can lead to starter failure or even damage to the engine. Threadlocker helps prevent this by keeping the bolts securely in place.
- Temperature Changes – Temperature changes can also cause starter bolts to become loose. As the engine heats up or cools down, the metal of the bolts and the engine block expand and contract. Over time, this can cause the bolts to loosen. Threadlocker helps prevent this by providing a secure seal that is not affected by temperature changes.
- Protects Against Rust and Corrosion – Starter bolts, like many other fasteners on a vehicle, are exposed to the elements and can become rusty or corroded over time. This can weaken the bolts and cause them to fail. Threadlocker helps prevent rust and corrosion by providing a barrier that protects the bolts from moisture and other harmful elements.
Types of Threadlocker
Threadlocker comes in different strengths, colors, and formulas. There are three main types: low strength, medium strength, and high strength.
- Low Strength – Low strength threadlocker is ideal for fasteners that require easy disassembly without the use of heat or special tools. It provides enough strength to keep the bolts securely in place but allows for easy removal when needed.
- Medium Strength – Medium strength threadlocker is ideal for fasteners that require a stronger hold but may still need to be removed for maintenance or repairs. It requires the use of heat or special tools to remove.
- High Strength – High strength threadlocker is ideal for fasteners that require a permanent bond, such as those in high-vibration environments. It is extremely difficult to remove and often requires the use of heat and special tools.
How to Use Threadlocker on Starter Bolts
Using threadlocker on starter bolts is a simple process:
