3. Strong Connection The hexagonal head provides an excellent grip, allowing for greater torque to be applied during installation. This results in a stronger, more secure connection than traditional screws, which is particularly important in structural applications where safety and stability are paramount.

Expanding metal wall anchors, often referred to as expansion anchors or toggle bolts, are hardware devices used to secure objects to walls or ceilings. They are constructed from metal and feature a unique design that allows them to expand within the wall when screw tension is applied. This expansion locks the anchor in place, providing a strong hold that can support significant weight.

Self-drilling screws, also known as Tek screws or self-tapping screws, are engineered with a drill bit tip that allows them to penetrate materials without the need for a separate drilling operation. This feature is particularly advantageous when working with thick steel, as it reduces the time required for assembly and helps ensure a secure, tight fit.

1. Time Efficiency The self-drilling capability eliminates the need for pre-drilling, saving considerable time during installation. This makes them ideal for situations where speed is essential, such as in large-scale construction projects.
