Product Overview
Our 18-400 Silver Aluminum Screw Top Cap features a brushed aluminum finish, providing a distinctive and attractive look that enhances your product's packaging. These continuous thread caps include a single thread inside the skirt, generally necessitating a full turn to achieve proper closure.
Ultimately, this silver aluminum screw-top cap is compatible with any jar that has a 18-400 neck size, where the first number denotes the container’s opening diameter in millimeters, and the second number indicates the thread depth on the cap’s skirt.
