Self Tapping Screw Manufactory

General self-tapping screws refer to screws with pointed self-tapping heads.

Self-tapping screws are used for non-metallic or soft metals without pre-drilling; self-tapping screws are pointed so that they can “self-tapping”; ordinary screws are flat-headed and of the same thickness.

Self-tapping screw means that the drilled hole is a hole that does not need to be tapped. The screw used is different from the general one. The head is pointed and the pitch is relatively large. It can be screwed in directly without tapping. Metal and plastic usually use this method. .

Our Self-Tapping Screws are designed to be versatile and adaptable, making them suitable for a wide range of applications. Whether you're working on a DIY project or a commercial construction project, our Self-Tapping Screws provide a reliable and easy-to-use fastening solution.

Durable Material

Our Self-Tapping Screws are made from high-quality steel that is corrosion-resistant and long-lasting, providing a reliable and durable fastening solution that can withstand harsh environments and heavy use.


A self-tapping screw is a type of fastener that can create its own threads as it is screwed into a material. This means that you don’t need to create threads in the material beforehand, making them convenient for certain applications.

Self-tapping screws are a type of fastener that are designed to create threads as they are screwed into a material. They are commonly used in applications where pre-drilling is not possible or desired, such as in thin metal sheets.

A self-tapping screw into metal is a fastener that can create its own threads as it is screwed into a metal material. This means that you don’t need to pre-drill holes for the screw, making it a convenient option for metal applications.

A 3/16-inch self-tapping screw typically requires a 5/32-inch drill bit. For a #14 self-tapping screw, you would typically need to drill a hole that is slightly smaller than the screw’s diameter, around 3/16-inch.

Yes, self-tapping screws can be used in wood, although they are more commonly used in metal applications. It’s important to choose the right length and gauge of screw for the thickness and type of wood being used.

A self-tapping screw has a specially designed tip that can create its own threads as it is screwed into a material. The tip of the screw cuts into the material, creating a path for the threads to follow as the screw is turned. As the screw turns, it continues to cut threads into the material, creating a secure and tight fit.

Self-tapping screws can come in a variety of shapes and sizes, but they typically have a pointed tip and threads along the length of the screw. Some self-tapping screws may also have a fluted or serrated shank to help remove material as the screw is inserted.

To use self-tapping screws for metal, first, make sure you have the correct size and gauge screw for the material you are working with. Then, use a power drill or screwdriver to insert the screw into the metal, using firm but gentle pressure to avoid stripping the threads. You may also want to use a lubricant or tapping fluid to help reduce friction and make the screwing process easier.

A 4mm self-tapping screw typically has a gauge size of around #8 or #10. The length of the screw will depend on the thickness of the material you are working with.

The size of the drill bit you should use for self-tapping screws will depend on the size and gauge of the screw you are using. As a general rule, the drill bit should be slightly smaller than the screw’s diameter.

Self-tapping screws are a type of screw that are designed to create their own threads as they are driven into material, without the need for a pre-drilled hole. Here are the steps to use self-tapping screws:

1.Choose the right size and type of self-tapping screw for the job. Self-tapping screws come in different sizes, lengths, and materials, so select the appropriate screw for the material you will be working with. You can also choose between different head types, such as flat, pan, or round.

2.Align the screw with the material you will be fastening. Hold the screw in place and apply gentle pressure while turning it clockwise to start the screwing process. If you are using a power tool, make sure it is set to the correct speed and torque setting for the screw size and material.

3.Continue turning the screw until it has penetrated the material and created its own threads. Be careful not to overtighten the screw, as this can cause the material to strip or crack.

4.Repeat the process for additional screws as needed. Make sure to space the screws evenly and use the appropriate number of screws to securely fasten the material.

Overall, using self-tapping screws is a relatively simple process that requires the right tools and a little bit of practice. With the proper technique, you can quickly and easily fasten materials together without the need for a pre-drilled hole.
