Rawl bolts are a specific type of what category of construction fasteners?

Rawl bolts are classified as anchor bolts, which are designed to secure structures to concrete or masonry surfaces. They are pivotal in applications requiring a strong, stable, and permanent anchoring solution. Rawl bolts utilize a sleeve that expands within the material they are anchored into; this ensures that the bolt is held securely in place and can withstand significant loads or stresses.

In construction, anchor bolts like Rawl bolts are essential for ensuring that frameworks, such as steel structures or wooden beams, remain securely attached to their base. This prevents any movement that could lead to structural failure over time. Their design and mechanism allow them to grip the surrounding material effectively, which is why they are specifically categorized under anchor bolts rather than other types of fasteners.

Decorative fasteners, light fixtures, and temporary supports serve different purposes and functionalities—decorative fasteners enhance visual appeal, light fixtures provide illumination, and temporary supports offer transient stability during construction. None of these fulfill the critical anchoring role that Rawl bolts are specifically engineered for.
