Expansion Bolt - Overview

An expansion bolt, also known as an anchor bolt, is a type of fastener designed to create a strong and secure hold in solid materials like concrete or masonry. It works by expanding within a pre-drilled hole when tightened, creating a wedge or sleeve that grips the surrounding material.
