Self-drilling screw

Self-drilling screws are designed for speed and convenience. They have the dual purpose of drill and screw without the need for pre-drilling.

Quick installation: no need to switch between the bit and the screwdriver bit.

Efficient design: The tip of the screw acts as a drill, while the notch area acts as a container for collecting wood or metal chips. This design allows the screw to create space for itself while drilling.

Material: Usually made of hard steel or materials such as 410 stainless steel that have been treated to enhance hardness.

Tapping screw

These screws are designed to create threads when screwed into pre-drilled holes, eliminating the need for a separate tap.

Cost and time efficient: No need for separate faucets, saving time and money.

Accuracy: Create precise threads for tighter, stronger connections.

Versatility: Commonly used in steel and masonry, but also suitable for plastic and wood.

Conclusion

Choosing the right screw for your project is crucial. Self-drilling screws and self-tapping screws have their own unique advantages. Understanding their differences and uses will help ensure the success and durability of your project.
