Toggle

• A toggle bolt is a long screw with a spring-loaded toggle on the end. The user must drill a hole in the wall large enough for the bolt to pass through. Attach the bolt to the end of the screw, hold the toggle bolt closed and insert it into the wall. Once released on the other side of the wall, the toggle opens and holds the screw in place.
  
  

Plastic

• Plastic anchors are either smooth or ribbed. The ribbed plastic anchors work best in drywall, while the smooth anchors are more suited for concrete or brick. The user must drill a hole in the wall and hammer the plastic anchor into place. When the screw enters the anchor, the anchor expands slightly, gripping the drywall to hold the fastener in place.
  
  

Molly Bolt

• A molly bolt is a bolt sleeve with a center screw. The user hammers the entire unit into the wall and tightens the screw with a screwdriver to expand the sleeve casing around the screw on the back side of the drywall. This expansion holds the anchor securely in place.
  
  

Sleeve

• A sleeve anchor is an expansion anchor similar to the molly bolt but is designed for concrete and brick installations. The installer drills a hole in the masonry large enough for the anchor. The installer then slides the anchor through the item being secured and into the hole in the masonry. Tightening the bolt on the end of the anchor expands the sleeve around the base, which holds the anchor and the item being attached in place.
