Butterfly toggle anchors are used together with various diameter specification metal screws.They are ideal for anchoring and fxing in the hollow,cavity substrate materials or the ceilling place.The high class PA-Nylon materias used to produce them provide the strong toughness and hardness with corrosion resistant. During installation, to make a pre-drilled hole is required.Butterfly toggle bolts are suited for indoor applications and expanded with matching combination-drive screws.
Two more wings are designed and added in the middle chamber. When the screws are used for fastening, the upper and lower ends are tightly held, so the novel design makes the two wings more support the load force. When being folded, the two wings will automatically retract and the outer two wings will not affect the insertion into the pre-drilled guide hole.
Suggest to use with stainless or brass screws in wet climates when anchor is flush, use provided pin to expand anchor behind drywall for vibration and shock loads.
