Self-drilling screws, also known as “Tek” screws, feature a unique design that incorporates a drill bit-like tip, allowing them to create their own hole as they are driven into materials. This feature eliminates the need for pre-drilling, saving time and effort during installation. Galvanized screws, on the other hand, are coated with a layer of zinc to enhance their corrosion resistance. This dual functionality makes self-drilling galvanized screws ideal for a wide range of applications, especially in outdoor and critical structural projects.

Another key advantage of using resin anchors for concrete is their ease of installation. Unlike traditional anchors that require drilling, tapping, or welding, resin anchors can be easily applied using a simple, straightforward process. First, the anchor hole is drilled into the concrete surface, then the resin adhesive is injected into the hole using a specialized dispenser. Once the resin is cured, the fixture can be securely attached to the concrete surface.

Aircraft structural fasteners come in various forms, including bolts, nuts, rivets, screws, and pins. Each type of fastener is designed to perform a specific function, whether it's providing a secure connection between two parts or allowing for easy disassembly and reassembly of components for maintenance and repairs. These fasteners are typically made from durable materials such as stainless steel, titanium, or aluminum, which are chosen for their strength, corrosion resistance, and lightweight properties.
