KA nickel plated flat head self tapping cross groove countersunk self tapping screw electronic small screw wholesale M3/M4/M5

Product advantages:Suitable for use in dry, non-corrosive environments

The countersunk design does not protrude:The head features a countersunk (flat head) structure, which can be embedded into the surface of the workpiece after installation, without being exposed or scratching. It maintains the flatness and aesthetics of the assembly surface, making it particularly suitable for furniture, equipment panels, decorative parts, and other scenarios where appearance flatness is required.

Cross slot is easy to operate:The cross slot type is compatible with universal cross screwdrivers, ensuring accurate positioning and reduced slippage during disassembly and assembly (compared to the straight slot). Both manual and electric tools can operate efficiently, reducing assembly difficulty.
