Abstract
An improved pin drive anchor has an elongated body with an inner end with a reduced section about which a locking sleeve member is secured, and a longitudinal bore extending the length of the body and having a reduced diameter section proximate to the sleeve member. The sleeve member and the body inner end are slotted to permit expansion of the sleeve member and the inner end when a pin is driven through the entire length of the body bore to firmly secure the anchor in the cavity of a wall.
