The integrated EPDM washer forms a tight seal around each screw penetration, preventing water from seeping beneath roof panels. EPDM rubber is resistant to UV rays, ozone, moisture, and extreme temperatures. This long-lasting waterproofing protects the roof from leaks, mold, and structural damage, making these screws suitable for all climates. Screws exposed to outdoor elements are susceptible to rust and deterioration. Waterproof screws with painted or coated heads provide superior corrosion protection.

Blind rivets are the perfect solution when only one side of a joint is accessible. Their one-sided installation system allows for fast, efficient assembly without the need for nuts, bolts, or welding, saving time and labor while ensuring a permanent, vibration-resistant connection. These features make them ideal for rooftop panels, curtain walls, HVAC ducts, vehicle assemblies, marine structures, and industrial enclosures. Each rivet guarantees consistent clamping force and maintains joint integrity in challenging environments.

The core advantage of drilling screws lies in their meticulously engineered tip and thread profile. The tip is designed to cut into a range of materials—metal, wood, composites—without damaging the surrounding surface. Once the screw engages, the threads provide a firm, vibration-resistant grip, ensuring long-term stability even under dynamic or heavy load conditions. This precision makes drilling screws particularly valuable in projects where maintaining material integrity is critical, such as machinery assembly or structural components.

Another frequent problem is difficulty driving screws into tough surfaces. Ordinary screws often require pre-drilled holes, slowing down work and increasing the risk of splitting or cracking the material. Our drilling screws incorporate sharp, self-drilling tips that penetrate metals, plastics, and laminated materials with ease. The reinforced tip creates a clean and accurate entry point, eliminating the need for pilot holes in many applications. This design accelerates installation, reduces labor, and ensures a professional-quality finish on every project.
