Self Drilling And Wood Screws

From hanging shelves to building furniture, our Self Drilling and Wood Screws are versatile enough to handle a wide range of applications. The self-drilling feature eliminates the need for pre-drilling, making your projects faster and more efficient.

Self-drilling screws are a type of screw commonly used in construction, woodworking and other applications. They differ from self-tapping screws in that they can be drilled and tapped at the same time. The screws have a bit like tip with spiral grooves or cutting edges that remove material when the screws are screwed in. The drill creates a hole, and the threads are then tightly attached to the material, providing a firm hold.

How to use self-drilling screws

1, if the total number of installations is small, you can also use a simple way, that is, matching the specification of the bolt and the nut. First, the self-tapping screw sleeve is fixed on the matching screw, and the same type of nut is fixed, and then the wrench tool is used to screw the screw into the bottom hole, and then the screw can be withdrawn.

2, if the total number of installations is large, it is recommended to use special screw sleeve installation tools, such as hexagonal head, tapping wrench tools, can also use pneumatic wrench.

Working principle

Self-tapping screw is a kind of screw with a drill bit, which is constructed by a special electric tool, drilling, tapping, fixing and locking are completed at once. And the general screw must have a processed screw hole to screw in.
