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.

Best for securing heavy machinery with constant motion, such as vibrating feeders and conveyors, to walls and floors, these anchors won’t shake loose. As you hammer in the pin, the anchor body expands while the ridges bite into your hole’s walls for a superior grip. These anchors require more force to install than sleeve anchors, so the block and brick you are installing them in should not be worn or cracked.

To install, position the nut and insert the anchor through your machinery into a drilled hole. Then, hammer the pin until it's flush with the top of the bolt, ensuring the anchor is fully set.
