Heavy-duty expansion anchors are mechanical anchors that create a secure hold by expanding within a drilled hole in concrete or masonry. As the anchor is tightened, the anchor body expands against the walls of the hole, ensuring a tight grip that can safely hold heavy loads. These anchors come in various materials, including steel and stainless steel, which are chosen based on the environment and load requirements.

Another key benefit of 5% self-drilling screws is their ease of use. The self-drilling feature eliminates the need for separate drilling equipment, saving time and effort during the installation process. With a compatible screwdriver or drill, users can quickly and easily drive 5% self-drilling screws into place, making them a popular choice for both professionals and DIY enthusiasts.
