The TOGGLER Toggle TA hollow-door anchor provides a firm hold in 1/8"- to 1/4"-thick hollow-core doors and thin panels, includes #8 x 1-1/4" screws, and is made in USA. The anchor is made from polypropylene that resists corrosion, is nonconductive for anchoring electrical components, and is low-friction to facilitate screw installation. The anchor hammers into a 5/16" drilled hole until flush with the mounting material's surface. Before the screw can be inserted into the anchor to create a secure hold, the included key is used to open the anchor's wings behind the material. The fins on the anchor head grip the mounting material to prevent spinning when a screw is inserted, and the anchor will stay in place if the fastener is removed, facilitating fixture and screw changes. If using screws other than those supplied, the anchor accepts #8 to #12 size screws with a minimum thread length of 1". The Toggle TA anchor meets Federal Specification FF-B-588-D for Type IV anchors.
