A Comprehensive Guide to Slotted Copper Machine Screws: Versatility in Industrial Applications

Slotted copper machine screws find widespread usage across various industries, owing to their superior material properties and versatility in fastening applications. Copper, known for its high electrical and thermal conductivity, offers numerous advantages, making these screws suitable for a broad range of projects.

Understanding Slotted Copper Machine Screws

Slotted copper machine screws are characterized by their cylindrical shape, threaded exterior, and a single slot cut into the head. The slot allows for easy tightening and loosening using a standard screwdriver. These screws are typically manufactured from C110 copper, which provides exceptional durability and corrosion resistance.

Key Advantages of Slotted Copper Machine Screws

1. High Electrical Conductivity: Copper possesses exceptional electrical conductivity, making these screws ideal for electrical applications requiring the efficient transfer of electrical current.

2. Corrosion Resistance: Copper resists corrosion and oxidation effectively, ensuring a long service life, even in harsh environments.

3. Non-Magnetic: Unlike ferrous materials, copper is non-magnetic, making these screws suitable for applications where magnetic interference is undesirable.

4. Heat Resistance: Copper exhibits high heat resistance, withstanding temperatures up to 200°C, ensuring reliability in high-temperature environments.
