The Wej-It PD58 POWER-Drop internally threaded drop-in anchor includes a wedge mechanism to create a secure hold within solid masonry and solid uncracked concrete, and meets 2000 International Building Code and 2000 International Residential Code specifications. The anchor body and wedge clip are made of corrosion-resistant zinc-plated carbon steel. The wedge clip expands within the drilled hole to secure the anchor in place. A safety shoulder above the clip provides support when the anchor is under severe strain. When installed, the anchor does not protrude from the drilled hole, enabling flush anchoring of an object to the mounting surface. The anchor"s allowable values may be increased 33.3% for short-term loading in resisting earthquake or wind loads.The included setting tool is externally threaded and has a washer and nut that can be placed to achieve a desired anchor depth. Once the setting tool has been threaded into the anchor and the anchor has been placed into the drilled hole, a hammer or mallet (sold separately) is used to drive the setting tool downward until the nut contacts the mounting surface. Tightening the nut sets the anchor and releases the setting tool from the anchor. An item can be mounted by inserting a threaded fastener (sold separately) through it and into the anchor.SpecificationsAnchorDrill DiameterMin. Hole DepthMin.

For more information, see the specifications sheet.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.
