2. Types of Key-Lockable Lock Pins

a. Threaded Key-Lock Pins

• These pins feature a threaded body and a locking mechanism that can be secured with a key.

• The key is used to tighten or loosen the locking mechanism, ensuring the pin remains securely in place.

b. Push-Button Key-Lock Pins

• These pins combine a push-button release mechanism with a key-lock feature.

• The button allows for quick release, while the key ensures the pin cannot be removed without authorization.

c. Cam Lock Pins with Keys

• Cam lock pins use a rotating cam to secure the pin, and a key is required to lock or unlock the cam.

• This design is often used in applications requiring high security and resistance to tampering.
