Combination screws can usually be divided into the following types:
1. Steel combination screw
This is a common combination screw, with the screw part made of steel material, typically a threaded screw.
2. Stainless steel combination screw
This combination screw is made of stainless steel material and has corrosion resistance. It is commonly used in environments or assemblies that require rust prevention.
3. Brass combination screw
This combination screw is made of brass material, which has good conductivity and corrosion resistance, making it suitable for applications that require electrical conductivity.
4. Aluminum alloy combination screw
This combination screw is made of aluminum alloy material, which is lightweight, has good corrosion resistance and thermal conductivity, and is commonly used in applications that require lightweight design.
5. Never loosen the screw
A loose screw, literally understood, means a screw that is both loose and will not come off. Also known as loose screws, spring screws, or non loose screws. It is used for riveting or expanding on installation plates, chassis and cabinets in various industries.
