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.

Others may feature an expandable sleeve that flares out at the end of the shank, anchoring the bolt firmly in place upon insertion.
