Product Description

 

Product Description

Self-tapping screws are fasteners that can directly thread into materials without pre-drilled holes, widely used in various scenarios due to their convenience and self-tapping properties. In furniture manufacturing, they are commonly used for quick assembly of wooden panels, such as connecting wardrobes, tables, and chairs, eliminating the need for pre-drilling to improve efficiency. In construction and decoration, they are suitable for fixing lightweight structures like gypsum boards and metal keels, especially for connecting thin steel plates (thickness ≤3mm). In electronic product assembly, small-sized self-tapping screws (e.g., M2-M4) secure casings and circuit boards, meeting precise installation requirements. The automotive industry uses them for rapid installation of interior components and body panels.

 

Specifications are divided by thread types into self-tapping (ST) and cutting (CS), with diameters typically ranging from M2 to M12 and lengths from 10 to 100mm. Materials include carbon steel (galvanized for rust prevention), stainless steel (corrosion-resistant), and aluminum alloy. During installation, torque must be controlled to prevent material cracking, and they are compatible with electric screwdrivers or pneumatic tools. With their "twist-to-fix" feature, self-tapping screws are the preferred solution for joining wood, thin metal sheets, plastics, and other materials, widely serving DIY projects, industrial manufacturing, and construction.
