Chemical anchor bolts utilize a resin-based adhesive to bond the bolt to the substrate, typically concrete. This method of anchoring offers several advantages over traditional mechanical anchors. The chemical bonding ensures a high load capacity and allows for a deeper embedment in concrete, which results in superior resistance to pull-out forces. Unlike mechanical anchors that rely solely on friction, chemical anchors distribute loads more evenly and significantly improve the overall performance of the fastening system.
