Understanding Hex Head Self-Tapping Screws with Washer Key Features and Applications

Self-drilling screws, often referred to as Tek screws, are equipped with a drill bit-like tip that enables them to drill through metal and other hard materials. These screws are typically made from high-strength materials such as carbon steel or stainless steel, which grant them exceptional durability and resistance to corrosion. Self-drilling screws come in various sizes and lengths, suitable for different applications, from roofing and siding to metal framing and vehicle construction.

3. Drop-In Anchors These anchors are designed for use in solid concrete and can be installed flush with the surface. They provide a strong, discreet solution, particularly useful for applications where a clean finish is required.

2. Vibration Absorption In mechanical applications, machines and equipment often experience vibrations during operation. Rubber washers act as shock absorbers, reducing the impact of these vibrations on the screw and the surrounding materials. This can prolong the life of both the fastener and the assembly it secures.

- Thread Design The thread design can influence the screw’s holding power. Coarse threads often provide better grip in thicker materials, while finer threads may work better in softer materials.

The process of galvanization involves coating the steel screw with a layer of zinc to protect it from rust and deterioration. This makes self-drilling galvanized screws particularly suited for applications in construction, roofing, and outdoor furniture, where exposure to moisture and other environmental conditions is prevalent.
