Bolts are beveled under the head for use in countersunk holes. A spring-loaded toggle holds against the back of the material. To install, insert the bolt through your fixture and thread the toggle onto it. Next, fold the toggle wings flush against the bolt and push them through a drilled hole until they pop open on the other side. Pull back on the bolt and tighten. In denser materials such as high-strength concrete, use a drill bit that is 1/16" larger than the size listed.

Bolts are zinc-plated steel to resist corrosion in wet environments. The bolt is reusable, but the toggle will fall behind the wall when the bolt is removed. Extra toggles are sold separately.
