CM plated black cross flat head screw, flat head screw, thin head computer screw wholesale M2/M3/M4/M6

The core advantages of black flat head screws are "stable fit, safe and scratch resistant, concealed and beautiful, and corrosion-resistant foundation"

• Big flat head design, strong fit and uniform force distribution: The head is a large-diameter flat structure with a contact area 2-3 times larger than ordinary round head and countersunk screws. After tightening, it tightly adheres to the surface of the workpiece, effectively dispersing fastening pressure and avoiding embedding in soft substrates such as wood and plastic (preventing substrate cracking and indentation); At the same time, the force is more balanced, and it is less likely to loosen under slight vibrations. Its fastening stability is better than that of small head screws, especially suitable for soft or thin substrates.
• Black surface treatment, excellent concealment and wide adaptability: The surface is often treated with oxidation blackening, electrophoretic blackening, etc., presenting a uniform black matte or glossy texture, which can perfectly integrate into dark workpieces (such as black plastic, dark wood, black metal shells). The screws are not abrupt when exposed, and the visual concealment is much better than silver and galvanized screws; At the same time, the black color is versatile and does not damage the overall appearance of the assembly surface, making it suitable for scenes with basic requirements for appearance
• Safe and scratch free, suitable for contact scenarios: The large flat head edge has been smoothly chamfered without sharp edges. It will not scratch clothing, skin or adjacent precision parts during daily contact, with high safety, especially suitable for frequent contact or exposure scenarios such as furniture, home accessories, electronic device casings, children's products, etc
