304 Stainless Steel CM Countersunk Head Hex Socket Screw – Flat Head Machine Screw
High-Quality 304 Stainless Steel Material
Contains 18% chromium and 8% nickel, with corrosion resistance far superior to ordinary carbon steel screws, suitable for harsh environments such as humidity and acidic or alkaline conditions. Formed using cold forging technology, with a hardness of HV180-220 and tensile strength ≥520MPa, ensuring long-term use without deformation.
CM Series Thin Flat Head Design
Extra-thin head (thickness only 60% of standard flat head screws) reduces installation space, suitable for compact scenarios like precision equipment and electronic instruments. The large flat head contact surface provides even force distribution, preventing the screw head from sinking or loosening, enhancing connection stability.
Internal Hex Drive Advantages
Hexagonal recess design compatible with standard hex wrenches, ensuring high torque transfer efficiency and avoiding slippage risk. The countersunk head allows the screw to sit flush with the workpiece surface, providing a tidy appearance and suitable for applications with high aesthetic requirements (such as furniture and decorative panels).
Universal Specifications Coverage
Available in full-size options from M2 to M12, with lengths ranging from 2mm to 50mm, and supports customized non-standard specifications. Meets standards and is compatible with globally mainstream device interfaces.
Application Scenarios
Industrial Equipment: Securing precision components of machine tools and automated machinery.
Outdoor Facilities: High weather resistance requirements, such as solar panel brackets and ship accessories.
Furniture Manufacturing: Concealed installation to enhance product appearance.
Electronic Instruments: Ultra-thin head prevents interference with internal components.
