Metal expansion nuts, often referred to as expansion anchors or expansion inserts, are specialized fasteners that expand when a bolt or screw is threaded into them. They typically consist of a cylindrical body with slits along its length or an expandable design that facilitates outward expansion. The main purpose of these nuts is to create a secure grip within a substrate, such as concrete, wood, or metal, thereby preventing loosening due to vibrational forces, temperature fluctuations, or stress.

The installation process for M24 chemical anchors is relatively straightforward. First, a hole is drilled into the substrate to the appropriate depth. Then, the anchor is inserted, followed by the chemical adhesive. As the resin cures, it expands, filling the void around the anchor and creating a strong mechanical bond with the surrounding material. This method ensures a high load-bearing capacity, making M24 chemical anchors ideal for supporting heavy loads in structural applications such as beams, columns, and machinery mounting.

The primary advantage of Stitch Tek screws lies in their exceptional holding power. The fine threading provides better penetration and grip, especially in dense materials like metal, wood, and composite boards. They are often used in applications requiring strong joints, such as in framing, roofing, and decking, where they can withstand immense loads without compromise. The robustness of Stitch Tek screws also makes them ideal for use in harsh environmental conditions, ensuring longevity and minimal maintenance.
