As a core component of roofing installations, this self-drilling roof screw eliminates the need for pre-drilled pilot holes, significantly streamlining the installation process while ensuring a secure connection between roofing materials. Equipped with a durable rubber washer, it provides exceptional waterproofing capabilities, preventing water infiltration and protecting the integrity of the roof structure. Whether used in residential, commercial, or industrial roofing projects, the TOPROPAN Roof Screw stands out for its durability, ease of use, and compatibility with different roofing systems.
Crafted with premium materials, the TOPROPAN Roof Screw prioritizes strength and corrosion resistance. The main body of the screw is made from high-quality stainless steel (available in grades suitable for diverse environmental conditions), which offers excellent resistance to rust, oxidation, and harsh weather elements such as rain, snow, and UV radiation. For enhanced durability, the screw undergoes professional galvanized surface treatment—this process forms a protective layer on the surface, further boosting its anti-corrosion performance and extending its service life. The integrated rubber washer is made of flexible, weather-resistant rubber that maintains its elasticity even in extreme temperature fluctuations, ensuring a tight seal and long-term waterproofing. Every step of the manufacturing process adheres to strict quality control standards, guaranteeing consistent performance and reliability of each Roof Screw.

To meet the unique needs of different projects, TOPROPAN offers flexible customization services for the Roof Screw:
Material Customization: Besides standard stainless steel, customers can choose other materials such as carbon steel or brass based on specific environmental and performance requirements.
Surface Treatment Customization: In addition to galvanization, options like nickel plating or black oxide treatment are available to match different aesthetic and corrosion-resistant needs.
Size Customization: The screw’s length, diameter, and thread specifications can be adjusted to fit non-standard roofing materials or special installation scenarios.
Washer Customization: Different types of washers (e.g., EPDM washers for enhanced weather resistance) can be selected according to project waterproofing and sealing demands.
Branding Customization: For bulk orders, customers can add their own logos or markings on the screw head to strengthen brand recognition (minimum order quantity applies).
No. The TOPROPAN Roof Screw features a self-drilling design with a drill bit-like tip, which can directly drill into metal, wood, and other roofing materials without pre-drilling a pilot hole. This saves installation time and improves work efficiency.
Yes. The screw is made of stainless steel and undergoes galvanized surface treatment, both of which provide strong corrosion resistance. It can withstand the high-humidity and salt-rich environment in coastal areas, avoiding rust and ensuring long-term use.
While the rubber washer is tightly integrated with the screw during production for optimal waterproofing, we offer replacement washers of the same specification. You can contact our customer service to purchase matching washers if needed.
