Product Description of Hexagon Socket Thin Head Cap Screws
- Function and use: The low head design allows these screws to be used in tight Spaces where standard cylindrical head screws cannot be fitted, while the hex bore allows high torque transfer during assembly.
- Applications: Widely used in the manufacture of precision instruments, electronics and equipment, especially in compact assembly and low-clearance applications where space is limited.
- Needs solved: These screws provide a reliable fastening solution in a limited space, ensuring that the components are firmly assembled without disturbing peripheral components.
