Flat head self-tapping screws, as defined by the GB5283 standard, are screws with a slotted countersunk head and self-tapping capability. These screws are designed to self-tap threads in materials without the need for pre-drilling or tapping.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Self-tapping function: capable of self-tapping threads without pre-drilling or tapping, suitable for a wide range of materials.

Flat head design: The flat head design allows the screw head to be flush with the surface of the material being secured, providing a neat appearance.

Slotted drive: The slotted design allows for manual installation with a screwdriver and is also suitable for use with electric or pneumatic screwdrivers.

High strength: according to GB/T 3098.5 standard, these screws have high strength mechanical properties and are suitable for applications with high load bearing requirements.

Scope of Application

Construction and Decoration: Used to fix plasterboards, wood panels and other decorative materials in construction and decoration projects.

Machinery and equipment assembly: for fixing components in machinery manufacturing and equipment assembly.

Repair and remodeling: in repair and remodeling projects, for reinforcing or fixing existing structural components.
