The versatile applications and uses of our metal screw sockets for lamp holders are predominantly seen in the following areas:
• Fixed bulb: The primary role of the metal screw in our lamp holder is to securely anchor the light bulb. Through the robust grip of the metal casing, the bulb is held firm and steady, safeguarding it from any displacement or vibration during operation.
• Conductivity: The metal screw seamlessly integrates with the power cord to deliver exceptional conductivity. As the bulb illuminates, the current elegantly flows through the metal screw, resulting in a radiant glow.
• Protecting the light bulb: Our metal screw is designed to endure various impacts and compressions, offering impeccable protection to the light bulb. This ensures the bulb remains unharmed and resilient against any external forces or pressures it may encounter during use.
