Self-fastening bolts, also known as self-locking or self-securing bolts, are typically made from high-strength materials such as stainless steel, carbon steel, or titanium alloys. They come in various sizes and styles, each tailored to meet specific industrial demands. For instance, some are designed with a built-in collet that grips the inner walls of the hole when tightened, creating a secure hold without the need for additional components. Others may feature an expandable sleeve that flares out at the end of the shank, anchoring the bolt firmly in place upon insertion.
