How a Hammer Drive Anchor Grips
A hammer-drive anchor sets by driving a nail through its body, which expands the anchor against the hole wall in one hammer stroke. It trades removability and heavy load capacity for speed, which is why it fits repetitive light-duty fastening rather than structural work.
