A bolt anchor, also known as a anchor bolt or anchor fastener, is a critical component in securing structures to foundations. It is designed to fix objects or structures to a concrete surface by anchoring them deep within the material. The design varies, with common types including expansion anchors, sleeve anchors, and anchor bolts with nuts and washers. They are made from materials like steel, stainless steel, or zinc-plated steel to withstand harsh conditions and heavy loads.
