A hex bolt sleeve, also known as a hex head sleeve anchor, is a type of expansion anchor designed for secure fastening to concrete, masonry, or other solid base materials. These anchors feature a hexagonal head and an expandable sleeve that provides a strong grip when installed in pre-drilled holes. Hex bolt sleeves are commonly used in construction, renovation, and industrial applications where a reliable and durable fastening solution is required.
