4 Core Advantages of Our Premium Waterproof Screws for Durability

Advanced Corrosion-Resistant Materials & Coatings

Crafted from 316 stainless steel, titanium Grade 5, or marine-grade brass, our screws resist saltwater, chlorine, and chemical corrosion. Proprietary PTFE/DLC coatings form a 3μm protective layer, passing 1,000+ hours of salt spray testing (ASTM B117) without rust—ideal for marine, 卫浴，and outdoor applications.

Multi-Seal Design for Absolute Waterproofing

Incorporate triple-layer waterproofing: thread-sealing PTFE tape, gasketed heads, and anti-loosening adhesives. This design achieves IP68 waterproofing (submersible up to 10m) and prevents water ingress in high-pressure environments like boat hulls or pool installations.

High-Torque Resistance for Long-Term Stability

Thread rolling technology enhances tensile strength by 40%, ensuring screws withstand 80N·m torque without stripping. Our anti-vibration design (serrated washers optional) keeps fastenings secure in dynamic wet conditions, reducing maintenance by 60%.

Custom Solutions for Diverse Applications

Offer 50+ head styles (hex, pan, countersunk) in sizes M3-M16, with custom lengths up to 150mm. Engineer-specific solutions for clients—e.g., self-drilling waterproof screws for PVC decks or UV-stabilized coatings for outdoor signage.
