In today's fast-paced world, threading inserts have become an essential item for industries that require high-quality connections between metal parts. Key locking inserts and self-tapping inserts are two types of threading inserts that offer different benefits. However, the key locking insert is known to perform better than self-tapping inserts. So, what makes the key locking insert superior?
First, let's understand what key locking inserts are. Key locking inserts are helically-coiled wire inserts that have external threads with a unique keyway design. They are usually made of high-strength steel and come in various sizes and lengths. On the other hand, Self-tapping inserts are cylindrical inserts with internal threads that are tapped into the parent material to form a connection.
One of the primary reasons why key locking inserts perform better is that they provide a stronger and more reliable connection. Key locking inserts are designed to distribute the load evenly across the parent material, preventing the material from being stripped or damaged. In contrast, self-tapping inserts rely on the quality of the parent material. If the parent material is weak, the self-tapping insert may not tap properly, resulting in a weak connection.
Another advantage of key locking inserts is their excellent resistance to vibration and loosening. The unique keyway design of the key locking insert creates a solid, tamper-resistant connection that resists both rotational and axial loads. On the other hand, self-tapping inserts rely on friction to maintain their connection, making them more susceptible to loosening. In high-vibration applications, self-tapping inserts may even come loose, causing damage or failure.
Furthermore, key locking inserts are easier and quicker to install than self-tapping inserts. Key locking inserts require only a simple drill and tap, whereas self-tapping inserts may require specialized equipment to install. Also, the installation of self-tapping inserts usually involves a longer process of drilling and tapping the hole, making it more time-consuming.
Overall, key locking inserts are the better option for industries where reliability, durability, and excellent resistance to vibration are needed. They offer a stronger, more reliable connection, are easier to install, and provide excellent resistance to vibration and loosening. While self-tapping inserts have their place, key locking inserts are the superior option for critical applications.
