Our strongest drive anchors are best for securing objects such as safety railings and warning signs. All have a rounded head that offers a finished look, won’t snag on objects, and is hard to grip, preventing unwanted removal. Often used for permanent installations, you can't remove your object without yanking the anchor out. These one-piece anchors compress when hammered in and expand inside a drilled hole, creating a powerful grip. No tightening is needed, making them quicker to install than wedge anchors.

To install, hammer the anchor through your object into a drilled hole until the head is flush with the surface. The installation force stresses your base material, so avoid using the anchor near edges, corners, or in cracked surfaces.
