PM coated black screw with cross groove round head electronic small screw and micro pan head screw M1/M2/M3/M4/M5

The core advantages of black round head cross screws are "safe and scratch resistant, concealed and beautiful, easy to disassemble and assemble, and corrosion-resistant foundation"

1. Round head design, safe and scratch free+gentle force: The head is a semi-circular spherical surface with smooth chamfered edges, without sharp edges. It will not scratch clothing, skin or adjacent precision components (such as internal circuits of household appliances and plastic shells) during daily contact, and its safety is much higher than that of countersunk and flat head screws with edges; At the same time, the round head is subjected to softer force, making it less likely to damage soft substrates such as wood and plastic due to excessive local pressure during tightening, and suitable for frequent contact scenarios such as furniture and children's products.
2. Black surface treatment, strong concealment+visual unity: The surface is often treated with oxidation blackening, electrophoretic blackening or blackening nickel plating, presenting a uniform matte/glossy black color, which can perfectly integrate into dark workpieces (such as black wooden furniture, black plastic shells, dark metal accessories). When screws are exposed, they are almost "invisible", and the visual concealment far exceeds silver and galvanized screws; And the black color is versatile and will not damage the overall appearance of the assembly surface, making it suitable for exposed fastening scenarios with basic requirements for appearance.
3. Cross groove drive, efficient disassembly and assembly, not easy to slip: The cross groove is accurately positioned, has a high degree of fit with the screwdriver/electric screwdriver, stable torque transmission, and is not easy to slip during disassembly (slot slipping and damage); Whether it's batch assembly in the factory, on-site decoration and construction, or personal DIY repair, it can be quickly operated and even beginners can easily get started, adapting to various construction scenarios.
