Nylon nail-in anchors are a type of concrete anchor that is installed by driving a nail into the anchor and then pushing the anchor into a pre-drilled hole in the concrete. The nylon body of the anchor expands within the hole, creating a secure bond with the concrete. These anchors are often used in applications where a quick, easy, and light load installation is required, such as securing small fixtures, or picture frames to concrete walls or ceilings. Nylon offers a better load bearing capability than Plastic, and does not deteriorate over time as quickly.
