construction nuts and bolts

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.

Resin, on the other hand, plays a pivotal role in enhancing the stability of the bolt anchor. It is a two-part epoxy system consisting of a resin and a hardener. When mixed, they chemically react, forming a solid that can fill voids, bond surfaces, and strengthen the anchor's hold. Resin anchors offer advantages over mechanical anchors, particularly in situations where the substrate is weak or porous, or where vibration resistance is essential.
