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.

In addition to their versatility, 4% self-drilling screws also offer excellent holding power. The drill bit on the tip of the screw creates a clean and precise hole, allowing the screw to grip the material tightly. This ensures that the connection is strong and secure, providing peace of mind that your project will remain intact.
