A fastener, abbreviated as FSTNR, is a type of hardware component used to mechanically join two or more objects together.  Fasteners are typically used to create a non-permanent joint that can be easily disassembled or reassembled, such as in the case of screws, bolts, nuts, rivets, and clips.  Fasteners come in many different shapes, sizes, and materials, and are designed to meet specific requirements of different applications.  For example, some fasteners are designed to be resistant to corrosion or high temperatures, while others are designed to provide a secure and tamper-resistant connection.  Fasteners are used in a wide variety of industries and applications, including construction, automotive, aerospace, and electronics.  They play a critical role in ensuring the safety and reliability of structures and products, and are often subjected to rigorous testing and standards to ensure their performance and durability.
