Pan Head Self Tapping Screw With Red Rubber Sealing Washer

Product Introduction

Pan head self tapping screw with red rubber sealing washer is a one-piece waterproof combination fastener specially designed for outdoor and sealed equipment assembly. The red elastic rubber washer is fixed between the screw head and the plate. When locked, the washer compresses to fill gaps, effectively blocking rainwater, dust and liquid from penetrating into equipment interior. The self-tapping thread features sharp tooth profile, which can cut threads on thin steel plates, aluminum plates and hard plastic without tapping holes in advance, greatly saving assembly time.
