Product Introduction：
The screw plug is available in two material versions: brass with nickel plating and nylon, catering to different cost, weight, and environmental requirements. The nickel-plated brass version offers high mechanical strength and electromagnetic shielding properties, suitable for heavy-duty applications such as industrial control cabinets. The nylon version is lightweight, insulating, and corrosion-resistant, ideal for sealing spare holes in general electronic devices or outdoor waterproof boxes. Thread types include PG and metric M series, with a round, low-profile head that can be hand-tightened without tools. This plug is primarily used to close unused cable entries, test ports, or drainage holes, effectively blocking dust, insects, and splashing water, thereby keeping equipment interiors clean and dry.
