expanding plastic screw anchors

The design of an M8 wedge anchor is simple yet effective. It consists of a threaded rod with a nut and washer, accompanied by a wedge-shaped expansion sleeve. When installed, the anchor is drilled into a pre-drilled hole in the concrete, and then the bolt is inserted and tightened. As the bolt is tightened, it pulls the wedge-shaped sleeve against the sides of the hole, creating friction and causing the sleeve to expand. This expansion locks the anchor securely in place, providing a strong hold that can withstand significant loads.

Chipboard, while inherently strong, can be susceptible to damage if not properly secured. Fasteners play a vital role in ensuring that the pieces of chipboard stay together under stress and use. They prevent joints from separating and maintain the overall integrity of the product, whether it’s a piece of furniture or a decorative shelf. Using the incorrect type of fastener can lead to stripped holes, poor support, and even failure of the assembled structure.
