Hex head screws are characterized by their six-sided heads, which allow for a secure grip with a wrench or socket. This makes them easier to tighten compared to other screw types, offering greater torque and reducing the risk of stripping. Made from materials such as stainless steel, carbon steel, and alloy steel, hex head screws are known for their strength and resistance to corrosion. Depending on the specific use case, screws can be designed with different coatings for added protection against rust and environmental factors.

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.
