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.

A wafer head screw, as the name suggests, has a flat, thin, and circular head, resembling a wafer. The head is usually larger than the screw's body, providing a broad bearing surface that distributes the load evenly and reduces the chances of damage to the material being fastened. The self-tapping attribute refers to the screw's ability to cut its way through the material it is inserted into, forming threads as it goes, hence the term self-tapping.
