Resin anchor bolts are specialized fasteners designed to provide a strong bond between the bolt and the substrate, often used in concrete applications. The primary feature that distinguishes resin anchor bolts from conventional anchors is their use of a chemical resin compound as the bonding agent. When the resin is mixed and injected into the drilled hole, it expands and sets, securely anchoring the bolt in place. This method is particularly advantageous in applications where traditional mechanical anchors may not suffice due to varying loads or environmental conditions.

Wafer head reamer self-drilling screws are specialized fasteners designed to penetrate materials without the need for pre-drilled holes. The wafer head refers to its flat, wide design, which provides a large bearing surface. This shape helps distribute the load over a broader area, reducing the risk of material deformation and enhancing overall stability. The reamer design, on the other hand, refers to the screw's cutting capability, allowing it to create its own hole while drilling into various substrates.
