Prevents water infiltration from the screw section! Sealed screws significantly enhance waterproofing and work efficiency. There's no need to wrap tape or apply sealing material.
The Eight Seal "Pre-coated Screw" is a type of screw with sealing material that eliminates the need to wrap tape or apply sealant to stop leaks. It prevents water intrusion from screws used for installing unit bath sashes, doors, and indoor drying racks. Since the sealant is pre-coated, it contributes to reduced total costs and uniform quality by shortening work time and improving production efficiency. The applied sealant exhibits excellent performance in terms of pressure resistance, oil resistance, and chemical resistance, and has a proven track record, so you can use it with confidence. Additionally, it has strong adhesion to various screw parts and completely protects the screw parts without any deterioration even after long-term storage. We not only sell Eight Seal pre-coated products but also accept requests for sealant application processing on supplied screws (such as small screws like M8, M10, plugs, etc.), so please feel free to consult us.
