Screws are another essential type of structural fastener, distinguished by their helical threads. They provide excellent holding power when driven into materials like wood, metal, or plastic. Common screw types include wood screws, machine screws, and self-tapping screws. Wood screws are designed specifically for use in wooden materials, while machine screws are used in conjunction with nuts or tapped holes in metal. Self-tapping screws, on the other hand, create their own thread as they are driven into the material, eliminating the need for pre-drilling.

There are several types of chemical fixings for concrete available on the market, each with its own unique properties and applications. Some common types of chemical fixings include epoxy adhesives, resin capsules, and injection systems Some common types of chemical fixings include epoxy adhesives, resin capsules, and injection systemschemical Some common types of chemical fixings include epoxy adhesives, resin capsules, and injection systems Some common types of chemical fixings include epoxy adhesives, resin capsules, and injection systemschemicalchemical fixings for concrete. Epoxy adhesives are ideal for bonding materials to concrete surfaces in both indoor and outdoor applications. Resin capsules are often used in heavy-duty applications where a high load capacity is required. Injection systems are typically used for repairing cracks and gaps in concrete structures.

Resin anchor studs are specialized fasteners designed to be installed into concrete and masonry substrates using a resin adhesive, typically an epoxy based solution. The studs are embedded into pre-drilled holes filled with the resin, which then cures to form a strong bond between the stud and the substrate. This anchoring method is particularly useful in environments where traditional mechanical anchors may falter due to high loads, dynamic forces, or the inherent variability of the base material.
