Used in lighter load applications, Hammer Drive Pin anchors attach fixtures to solid concrete, brick, block, or mortar. They are mostly used to secure plywood to concrete or to hang furring strips and metal brackets. Hammer drive pin anchors are also known as hammer-set anchors, drive pins, nail drive anchors, nail-on anchors, concrete anchor nails, and mushroom head anchors.
Drive pin anchors are very simple and easy to install. Using a pre-drilled hole, they are installed with a hammer strike, which drives the pin into the anchor body, expanding the anchor to form a tight fit. They do not need a separate screw for securing a fixture to the anchor like drop-in or double expansion anchors do. and Be wary of installing these into crumbly materials; they will not hold as well as more solid base materials.
Hammer-set anchors have a lip over the head, preventing the anchor from falling too deep into a pre-drilled hole. This makes these anchors compatible with holes that may have accidentally been driven too far into the material.
How to Install Hammer Drive Pin Concrete Masonry Anchors
How do I install hammer drive anchors?
After drilling the hole for the hammer-set anchor, place what you want to fasten over the hole, with its installation hole and the drilled hole in the base material lining up. Insert the drive pin anchor into the hole until the lip or mushroom head makes contact with the surface of the material you are fastening with its lower portion in the base material. Then, using a hammer, tap the anchor's protruding nail portion until it is flush with the anchor's head. Your drive pin anchor is now installed, and your application is now secure to the base material.
How do I remove hammer drive anchors?
Anchors for concrete, brick, block, and other masonry materials are not intended to be removed once they are set. If they were removable, they would not have nearly as strong holding power as they do. That being said, if you absolutely must remove this anchor, one way to do so would be to cut off the anchor's head using a hacksaw or cutoff wheel. There is a high chance you may damage the surface material with this method, so keep that in mind. Once the head is gone, you can drill out the body using a high-speed drill bit. It's tough to remove anchors once installed without damaging the fastening materials. Hence, we recommend being sure of your anchor placement first before installing it.
What are drive pins used for?
