The Wej-It WD38 internally threaded drop-in anchor is zinc-plated carbon steel, provides a secure hold within solid masonry and solid uncracked concrete, and meets GSA FFS-325 Group VIII Type 1 Federal Specifications. The one-piece carbon-steel anchor body is zinc plated for corrosion resistance. The body expands within the drilled hole to secure the anchor in place. When installed, the anchor does not protrude from the drilled hole, enabling flush anchoring of an object to the mounting surface.
Once the anchor has been placed into the drilled hole, the setting tool (sold separately) inserts into the threaded portion of the anchor and a hammer or mallet (sold separately) is used to drive the setting tool downward until its shoulder makes contact with the anchor, expanding the anchor within the hole. After the setting tool has been removed, an item can be mounted by inserting a threaded fastener (sold separately) through it and into the anchor.

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.
