5 inch self drilling screws

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.
