Mechanical fastening is a method used to join two or more materials together using physical components, such as screws, bolts, or rivets. This technique creates a strong connection that can be easily assembled and disassembled, making it popular in various industries, including construction and manufacturing. The process involves inserting a fastener through the materials to be joined and securing it in place. Mechanical fastening is often preferred for its reliability and ease of maintenance, as it allows for repairs or modifications without damaging the original materials.
