Key aspects of fasteners:

Function:  Fasteners are primarily used for mechanical joining, ensuring that parts stay together and maintain their intended position.
Types:  The world of fasteners is vast, encompassing threaded (screws, bolts, nuts, studs) and non-threaded (rivets, nails, and some specialized anchors) options.
Materials:  Fasteners can be made of various materials like steel, stainless steel, brass, plastic, and composites, depending on the application and desired properties.
Applications:  Fasteners are essential in a wide range of industries, including construction, manufacturing, automotive, electronics, and more.
Permanent vs. Non-permanent:  Some fasteners are designed for permanent connections (like rivets or welding), while others are designed for temporary or removable joints (like screws or bolts).
Standardization: Many fasteners have standardized dimensions, thread types, and materials to ensure interchangeability and compatibility.
