Our Nylon Head Self-Drilling Screws are engineered for high-performance fastening in structural metal manufacturing. Utilizing premium Carbon Steel (1022A) and adhering to the DIN 7504 standard, these screws integrate a precision-drilled point with a bonded nylon washer, eliminating the need for pre-drilling and providing an immediate, watertight seal for industrial applications.
Designed for durability and efficiency, these fasteners are ideal for metal roofing, wall cladding, and steel structures. With available coatings including Zinc Plated and Dacromet, they offer superior corrosion resistance and high holding power, ensuring long-term structural integrity even in the most demanding exterior environments.
| Material | Carbon Steel (1022A) | Standard | DIN 7504 / ISO 15480 |
|---|---|---|---|
| Head Type | Hex Head with Nylon Washer | Point Type | Self-drilling (#2, #3, #4, #5) |
| Strength Level | High-strength | Size Range | #6 – #14 (3.5mm – 6.3mm) |
| Surface Finish | ZP / YZP / Dacromet etc. | Length Range | 13mm - 150mm |
| Drilling Range | 0.7mm to 6.0mm (based on point) | Thread Size | ST2.9 to ST6.3 |
The bonded nylon washer compresses upon installation to prevent water infiltration, making it ideal for outdoor metal roofing.
Self-drilling tips eliminate pre-drilling, allowing for drilling, tapping, and fastening in a single efficient operation.
Multiple finish options like Dacromet and Galvanized ensure long-term durability against harsh environmental exposure.
Deep, precision threads provide an exceptional grip in steel substrates, ensuring the structure remains secure over time.
The nylon head design prevents scratching and damage to painted metal surfaces during the fastening process.
Strictly manufactured to DIN 7504 specifications to ensure global compatibility and consistent performance.
All standard sizes from ST2.9 to ST6.3 are maintained in stock for rapid global dispatch.
Rigorous testing for torque strength and drilling capacity according to DIN standards.
Custom head color matching available to seamlessly integrate with project aesthetics.
Flexible contractor quantities available: 250, 500, 1000, or 5000 pcs per box.
Optimized supply chain management for timely delivery to construction sites worldwide.
Expert guidance on matching drill points to specific metal thickness for maximum efficiency.
| Performance Metric | Standard Screws | Nylon Head Self-Drilling |
|---|---|---|
| Installation Speed | Slow (Pre-drilling req.) | Ultra-Fast (One-step) |
| Waterproofing | Requires Extra Sealant | Integrated Nylon Seal |
| Labor Cost | High (Multiple steps) | Low (Direct drive) |
| Surface Damage | High risk of scratches | Minimal (Nylon protection) |
| Maintenance Cycle | Frequent (Leak risk) | Extended (Weather-proof) |
Depending on the drill point (#2 to #5), our screws can penetrate materials ranging from 0.7mm up to 6.0mm. Please consult our size chart to match the point to your material thickness.
The bonded nylon washer creates a watertight compression seal when tightened, preventing moisture from leaking into the structure and reducing the risk of internal rust and leaks.
For high-corrosion areas, we recommend Dacromet or galvanized coatings, as they provide significantly higher salt-spray resistance compared to standard zinc plating.
We recommend using a variable speed drill set between 1500-2500 RPM. Ensure the drive is perpendicular to the surface for an optimal seal.
