Self Drilling Screws with EPDM Washer are designed for metal-to-metal and metal-to-roof fastening applications where waterproof sealing and corrosion resistance are critical. The integrated EPDM bonded washer provides long-term weather sealing, vibration resistance, and protection against leakage. These screws are widely used in steel roofing, wall cladding, and industrial buildings.

Export experience for EU, USA, Middle East & Australia markets
Self Drilling Screws with EPDM Washers are widely used in various applications, including:
Roofing and Cladding: These screws are commonly used for attaching metal roofing and cladding to the underlying structure. The EPDM washer provides a watertight seal, preventing water ingress and ensuring the integrity of the roof.
HVAC Systems: In heating, ventilation, and air conditioning systems, these screws are used to secure sheet metal components, such as ductwork, while maintaining an airtight and watertight seal.
Signage and Outdoor Displays: For outdoor signs and displays, these screws ensure that the sign remains securely attached to the mounting surface, even in harsh weather conditions.
Automotive and Transportation: In the automotive industry, these screws can be used for attaching panels and components where a waterproof seal is necessary.
Construction and General Building: They are used in general construction for fastening metal sheets, gutters, and other exterior building components, providing both structural integrity and a reliable seal.
Solar Panel Installation: In solar panel installations, these screws can be used to attach the panels to the mounting structure, ensuring a secure and weather-resistant connection.
Marine Applications: In marine environments, these screws are used for their corrosion resistance and ability to maintain a watertight seal, making them suitable for boat and ship construction.
Steel, stainless steel, and zinc or phosphate coatings that improve corrosion resistance are common materials.
