Chemical anchor bolts are specialized fasteners that utilize a two-part adhesive system to bond with the concrete substrate. Unlike traditional mechanical anchors that rely purely on physical expansion or friction to secure themselves within the concrete, chemical anchors use a resin or adhesive, which is mixed with a hardener, to create a strong bond. This resin is typically injected into pre-drilled holes in the concrete before the anchor bolt is inserted. As the resin cures, it forms a very strong adhesive bond with both the bolt and the concrete, leading to excellent load-bearing capabilities.

3. Material Quality The material of the butterfly screws can affect durability and performance. Look for screws made of high-quality metal, such as stainless steel, to avoid corrosion and ensure longevity.

Metal expansion nuts find their usage in diverse fields. In construction, they are frequently employed for securing structural elements, like beams and frames, in concrete. They are also prevalent in HVAC systems, where they help secure ducts and other installations prone to thermal expansion.
