Galvanized Tek screws are self-drilling screws designed for metal-to-metal or metal-to-wood connections. The term Tek refers to the screw's ability to drill its own hole without the need for a pre-drilled pilot hole. This feature not only simplifies the installation process but also saves time, making it a popular choice among contractors and DIY enthusiasts alike.

When it comes to woodworking, choosing the right fasteners is fundamental to achieving durable and aesthetically pleasing results. Among the plethora of options available, hex screws stand out as versatile and highly effective choices for various applications. Their design and functionality make them particularly well-suited for wood, providing both strength and ease of use.

Metal expansion nuts, often referred to as expansion anchors or expansion inserts, are specialized fasteners that expand when a bolt or screw is threaded into them. They typically consist of a cylindrical body with slits along its length or an expandable design that facilitates outward expansion. The main purpose of these nuts is to create a secure grip within a substrate, such as concrete, wood, or metal, thereby preventing loosening due to vibrational forces, temperature fluctuations, or stress.
