What is a Keylocking Threaded Inserts?
Locking Thread Inserts are specially designed fasteners used to provide strong, reliable threads in materials that may not be strong enough on their own, such as soft metals, plastics or composites. They are particularly useful in applications requiring high torque or load-bearing capabilities.
Keylock Thread Inserts Key Features:
Design: Keylock Inserts typically have a unique design that includes a key or locking feature that engages the parent material. This helps prevent the Insert from rotating or pulling out under load.
Material: They are usually made of durable materials such as stainless steel, brass or other alloys for strength and corrosion resistance.
Installation: The installation process typically involves drilling a hole, tapping it to create threads, and then inserting a keying insert. The keys on the insert engage the surrounding material, ensuring a secure fit.
Applications: Keylock thread inserts are often used in automotive, aerospace and industrial applications where high strength and reliability are critical. They are also used in situations where frequent assembly and disassembly are required.
Advantages of Keylock Thread Inserts:
Increased Strength: They provide a stronger wire than the base material alone, making them ideal for high stress applications.
Reusability: Many keylock inserts can be reused multiple times, making them cost-effective for applications that require frequent maintenance.
Versatility: They can be used on a wide range of materials including soft metals, plastics and composites.
Installation process:
The installation process for locking thread inserts is similar to the installation process for other thread inserts:
Drilling: Use a drill bit to create a hole of a specified diameter in the substrate.
Tapping: Use a tap to create threads in the hole that match the external threads of the insert.
Insert Keylock Insert: Insert the Keylock threaded insert into the threaded hole. Ensure the key engages properly with the surrounding material.
Secure the Insert: Depending on the design, you may need to use a special tool to ensure the insert is fully seated and locked into place.
Keylock Thread Inserts are an effective solution for enhancing the strength and durability of threaded connections in a variety of materials. Their unique design and installation process make them a valuable choice for applications that require a reliable and rugged fastening solution.
