Remove the bolt so the anchor is flush with your walls and floors to slide components past these anchors, making it easier to install or make adjustments. They’re best for door frames that need to be pressed into place or machinery you service frequently. All have a sleeve that expands inside your hole to create a strong grip. Since the gripping force is distributed along the entire length of the anchor, it won’t crack soft materials like block and brick. You can use these anchors as an alternative to wedge anchors in concrete near edges, corners, or other weak points, but they are not as strong.

To install, drive the anchor through your component into a drilled hole until the head meets the surface. Then, tighten the bolt to expand the anchor sleeve. As you tighten, the nylon ring compresses to secure the component against the surface. You can remove the bolt, but the anchor itself cannot be removed.
