Electroplated nickel surface treatment creates a uniform, dense nickel plating layer (5-10μm thick) that provides excellent corrosion protection and enhanced durability. The nickel plating isolates the carbon steel substrate from air and moisture, preventing rust in indoor environments. With higher surface hardness (HV 150-200), these screws resist wear on head slots during assembly/disassembly and maintain a clean, silver-white appearance ideal for electronic devices and office equipment.
Semi-circular spherical head with chamfered edges ensures safe handling without scratching skin, clothing, or precision components. The built-in washer eliminates need for separate flat washers, provides even pressure distribution, prevents substrate embedding in soft materials, and enhances anti-loosening performance for reliable fastening in furniture, appliances, and equipment assemblies.
Flat cutting end design enables smooth thread groove creation in soft substrates like plastic, wood, and thin aluminum (≤1mm) without pre-drilling. Prevents substrate cracking in brittle materials and eliminates back-side component damage, making installation efficient and safe for electronic casings, furniture hardware, and toy assemblies.
