Structural fasteners play a vital role in construction and manufacturing, providing the necessary strength and reliability to hold various components together. These fasteners can be categorized into several types based on their design, application, and mechanical properties. Understanding the different types of structural fasteners is crucial for engineers, architects, and builders, as selecting the appropriate fastener can significantly impact the structural integrity and safety of a project.

Wedge anchor bolts offer several advantages in construction. Their ability to provide a secure hold in concrete makes them ideal for both temporary and permanent installations. The installation process is relatively straightforward, requiring only the drilling of a hole, insertion of the wedge anchor, and tightening of the bolt to create a secure bond.

2. Strength and Stability The design of countersunk screws allows for a greater surface area contact with the material, leading to a more secure fixation. This increases the overall strength and stability of the assembled components.

The addition of washers to hex head self-tapping screws is another feature that enhances their performance. Washers are flat discs, usually made of metal or plastic, placed under the head of the screw. They serve several important purposes

1. Wedge Anchors One of the most common types, wedge anchors feature a conical end that expands when the bolt is tightened. They are best suited for solid concrete and provide excellent load-bearing capabilities.
