The advantages of self-tapping crosshead screws:

Easy to install: Self-tapping screws are designed to cut their own threads as they are driven into the material, which makes them easy to install without the need for pre-drilled holes.

Versatile: Self-tapping screws are versatile and can be used in a wide range of materials, including metal, plastic, and wood.

Stronger fastening: Self-tapping screws create a stronger and more secure fastening than regular screws because they create their own threads in the material, which helps to prevent the screw from coming loose over time.

Time-saving: Self-tapping screws save time and effort because they eliminate the need for pre-drilled holes or tapping threads. This makes them a popular choice for large-scale projects or for applications where time is of the essence.

Cost-effective: Self-tapping screws are often more cost-effective than other fastening methods because they require fewer steps and materials.
