In connection scenarios involving soft materials such as plastics, aluminum alloys, cast iron, or copper, insufficient material thickness often leads to loosening or failure of traditional threads. Self-tapping thread inserts provide a reliable solution for these scenarios by physically strengthening the thread structure. Domestic M3-M12 stainless steel three-hole self-tapping screw inserts, as an alternative to imported products, offer the core value of solving stability issues in soft material connections through structural optimization and material compatibility.
Iron, Copper, Aluminum: Self-tapping screws made of these materials are relatively inexpensive and suitable for applications where hardness and durability requirements are not high.
Alloys: Alloy self-tapping screws offer improved hardness and durability, suitable for various applications.
Titanium Alloys and Pure Titanium: These high-end self-tapping screws possess excellent hardness and corrosion resistance, suitable for applications requiring extreme environments and high strength, but are relatively expensive.
Thread Selection:
Coarse Threads: Suitable for thicker materials, providing a stronger fixing effect.
Fine Threads: Suitable for thinner materials, reducing material damage and improving durability.
