What are the two methods of fastening?

The two methods of fastening are mechanical fastening and adhesive fastening.

1. Mechanical fastening involves using physical devices such as screws, bolts, nuts, rivets, clips, or other fasteners to join two or more components together. This method relies on the friction and tension created by the fasteners to hold the components in place.

2. Adhesive fastening involves using adhesives or glues to bond two or more components together. The adhesive creates a strong bond between the surfaces of the components, holding them together securely. Adhesive fastening is often used when a seamless appearance is desired or when mechanical fastening is not possible.
