CHEESE HEAD MACHINE MICRO SCREW is a micro screw with a cylindrical head and a flat top. It is named because its head shape is similar to "cheese cylinder". This type of screw is widely used in precision machinery, electronic products, medical equipment and other fields. It has the characteristics of compact structure, firm installation, and suitable for high-precision connection.
2. Product features and professional data analysis
1. Head structure: Cheese Head
Feature description: The head is cylindrical, with a flat top and a diameter slightly larger than the screw, which is conducive to higher torque transmission.
Professional data:
Common head diameter (Head Diameter, D): 1.2mm ~ 6.0mm
Head height (Head Height, H): 0.4mm ~ 2.0mm
Advantages: Suitable for assembly of micro components with high torque requirements, improving fastening stability.
2. Thread type: Metric Fine Thread
Feature description: Fine thread provides higher self-locking ability and is suitable for anti-seismic and anti-loosening occasions.
Professional data:
Thread Diameter (M): M0.8 / M1.0 / M1.2 / M1.6 / M2.0, etc.
Pitch: 0.2mm ~ 0.4mm
Advantages: Suitable for high vibration environments, such as aerospace, automotive micro-motor components, etc.
3. Materials and surface treatment
Common materials:
Stainless steel (SUS304/SUS316): Strong corrosion resistance, suitable for medical devices.
Carbon steel (SCM435): High strength, suitable for load-bearing components.
Copper alloy (such as C3604): Good electrical conductivity, commonly used in electronic products.
Surface treatment method:
Nickel plating: anti-corrosion and anti-oxidation
Zinc plating: economical and practical
Black oxide: beautiful and rust-proof
Professional data:
Tensile strength: ≥ 600 MPa (carbon steel)
Surface roughness (Ra): 0.6μm ~ 1.6μm (for high-precision assembly)
4. Drive method: screw slot type
Common types include:
Phillips
Hex socket
Torx
Professional data:
Drive slot size is based on ISO standards, for example, PH000 is suitable for micro screws below M1.2
Advantages: avoid slipping and improve assembly accuracy.
III. Application scenarios
1. Consumer electronics industry
Applied in smart phones, tablets, laptops, cameras and other products to fix motherboards, screen brackets, battery modules, etc.
Typical case: M1.2×2.5 stainless steel cheese head screws used in iPhone motherboards.
2. Medical equipment
Applied to precision equipment such as micro-surgical equipment, insulin pumps, pacemakers, etc., requiring high cleanliness, corrosion resistance, and non-magnetic.
Material used: SUS316 stainless steel to ensure no biological reaction.
3. Optical equipment
Used for precision connection of internal components such as microscopes, telescopes, laser rangefinders, etc.
Requires the screw size accuracy tolerance to be controlled within ±0.01mm.
4. Aerospace/military industry
Micro radar modules, inertial navigation systems, etc. use such screws, which must meet the harsh environmental requirements of vibration resistance and high temperature resistance.
5. Watches and accessories
The connectors in Swiss watches and precision accessories must use micro fasteners, and have high requirements for appearance aesthetics
