Self tapping screw is a special type of fastener that can form threads on its own in the material being fixed, thereby achieving a fixing effect. The following are the main characteristics and components of self tapping screws:
characteristic:
1. Self tapping: The design of self tapping screws allows them to form threads on their own in holes without pre threading, as their tails are usually sharp and can be cut and threaded when screwing in materials.
2. Applicability: Suitable for various materials such as metal, plastic, wood, etc., especially suitable for thin-walled materials.
3. Efficiency: Since there is no need for pre drilling and threading, self tapping screws can be quickly installed, improving work efficiency.
4. Tightening force: The internal thread formed by self tapping screws can provide good fastening force, suitable for various fixing needs.
component:
1. Head: It usually has slots, such as cross slots, straight slots, etc., for easy rotation and installation using the corresponding screwdriver.
2. Threaded section: This section is designed to form threads in the fixed material.
3. Tip: A sharp tip is used to cut materials and form threads.
4. Body: The main part of the screw, providing necessary strength and support.
Category:
-Self tapping screws: suitable for soft materials such as plastic or wood.
-Self cutting screws: suitable for harder materials such as metal.
-Self drilling and self tapping screws: Combining the functions of self tapping and self cutting, they can simultaneously drill holes and form threads.
Self tapping screws have been widely used in various fields such as construction, furniture, and electronic product assembly due to their convenient installation method and wide applicability.
