Types of Expanding Wall Anchors

Self-drilling screws, often referred to as Tek screws, are specialized fasteners that possess a unique drill point. This drill point enables the screw to create its own hole in the material, eliminating the need for pre-drilling. When combined with the galvanized coating, which provides excellent corrosion resistance, these screws become ideal for outdoor and high-humidity environments.

In automotive applications, metal expansion nuts are utilized in securing engine components and exhaust systems, where high temperatures can lead to expansion. Their reliability ensures that parts remain firmly attached, reducing the risk of failure.

 In addition, the unique design of hexagonal flange bolts allows for easy installation and removal, saving time and effort in maintenance and repair work. Integrated washers eliminate the need for separate washers, simplifying the tightening process and reducing the risk of misalignment.

Nuts are used alongside bolts to secure components together. The nut’s internal threads allow it to fit onto the bolt’s shaft, creating a tight connection when tightened. There are several types of nuts, including hex nuts, lock nuts, and wing nuts. Lock nuts are designed to resist loosening under vibration, making them well-suited for applications in dynamic environments. Wing nuts, with their unique design, can be easily tightened or loosened by hand, making them useful in situations where frequent adjustments are necessary.
