Self-drilling anchors are designed with a screw point and cutting edges that allow them to cut through various substrates, including rock, concrete, and steel. They also have a thread section that allows for immediate load transfer after installation, providing immediate stability to the structure. This feature is invaluable in situations where immediate support is required, such as in slope stabilization, foundation repair, or even in temporary works during construction.

They act as the bridge between the concrete foundation and the superstructure, transferring loads from the structure to the ground. Their design varies, from J-bolts to U-bolts, each tailored to suit specific engineering requirements and soil conditions.

Hex socket head wood screws are a type of screw that features a hexagonal socket drive head. This design allows the screw to be driven by an Allen wrench, commonly known as a hex key. The head is often broader than that of traditional screws, providing a larger surface area that distributes pressure evenly when tightened and prevents the screw from being pulled into the wood. The threads on a hex socket head wood screw are specifically designed for optimal grip in wooden materials, ensuring a secure fit.
