304 Screw with Rubber Gasket Drill Tail

Name: 304 Screw with Rubber Gasket Drill Tail
Brand: Shenzhen Xintegu Hardware Co.,Ltd.

The 304 Screw with Rubber Gasket Drill Tail is designed for superior fastening performance in environments where moisture and air tightness are critical. Made from durable 304 stainless steel, this screw offers excellent corrosion resistance, making it ideal for outdoor or marine applications. The integrated rubber gasket provides a reliable seal, preventing water and air penetration at the point of entry, which is crucial for maintaining the integrity of structures and preventing corrosion under the screw head. The self-drilling tail feature allows for rapid installation without the need for pre-drilling, saving time and effort in assembly processes.
