The Wej-It Nail-It DN1412 drive anchor is made of zamac alloy and cold rolled steel, provides a secure hold in concrete, block, brick, and stone, and meets Federal Specification GSA FFS-325 Group V, Type 2, Class 2. The anchor body inserts into a drilled hole and a hammer (sold separately) drives the pin down into the body, expanding the body and gripping the mounting material. The anchor's mushroom head lies above the material surface when installed, and the nail enters the head when installed to create a tamper-resistant seal.

Anchors provide reinforcement to fasteners installed in materials that are considered brittle or have insufficient hold such as drywall, concrete, brick, and stone. Anchors provide support through methods such as expansion from within or behind the substrate, or insertion of adhesive compounds into drilled holes.
Wej-It Fastening Systems manufactures mechanical and adhesive fasteners for use in concrete and drywall. The company, founded more than 60 years ago, is headquartered in Norwalk, CT.
