Split drive anchors are typically made of metal

Split drive anchors are fasteners used to secure objects to concrete, masonry, or other materials. They are named "split drive" due to the split design on the tip of the anchor that allows it to expand and grip the material as the screw is driven into it.

Split drive anchors are typically made of metal, such as steel or stainless steel, and they come in various sizes to accommodate different screw sizes. They can be used in a variety of applications, including securing shelves, hanging light fixtures, or attaching brackets to walls.

To use a split drive anchor, a pilot hole is drilled into the material to be anchored, and the split drive anchor is inserted into the hole. The screw is then driven into the anchor, causing the split tips to expand and grip the material, securing the anchor in place. The screw can then be used to attach the desired object to the anchor.

Split drive anchors are known for their strength and versatility, making them a popular choice for many applications. They are easy to install and can be used with a variety of screws, making them a versatile fastening solution for concrete, masonry, and other materials.
