How to distinguish between Screw Slot and bayonet?
You can check the port of the machine pen. If the inside of the head is spiral, the needle that is screwed in through the screw is a screw-type needle.
If your machine is not a screw type, it is usually a type that requires a needle to be inserted directly into the pen. It is a Bayonet port. Please purchase it from other links in my shop.
