Plastic Wall Anchor
These anchors are often misused by people who try and use them in drywall applications. They're virtually useless in hollow wall applications such as drywall, and are designed to expand against a solid surface as the screw is tightened. These anchors are inexpensive but work OK if installed into plaster, masonry or some other solid material. Also, you want to drill the pilot hole for these anchors a little snug to create a tight fit so the anchor does not spin when you go to fasten the screw.
To install these anchors do the following:
- Drill a snug pilot hole.
- Tap the anchor into the hole using a hammer.
- Fasten the screw into the hole expanding the plastic anchor and tightening it against the solid substrate.
