Advantages of Self Tapping Metal Roofing Screws
1. No need to pre-drill, saving 50% of working hours
Integrated self-drilling tip design, the screw head comes with a high-hardness drill bit (such as carbon steel with titanium or tungsten steel).
Practical data proves:
Traditional installation process: pre-drilling (30 seconds/hole) → installing screws (15 seconds/hole) → total time 45 seconds/hole.
The installation process of this product: direct drilling + locking in one step → 20 seconds/hole, efficiency increased by 55%.
Applicable scenarios: metal roofs (0.5-1.2mm thickness), wooden purlins, PVC sheets.
2. Super corrosion resistance, life of up to 20 years
Material and process:
304 stainless steel: salt spray test (ASTM B117 standard) 1000 hours without rust, suitable for coastal/high humidity areas.
Carbon steel galvanized (optional): zinc layer thickness ≥12μm, passed 200 hours of salt spray test, more cost-effective.
Comparative advantages:
Ordinary galvanized screws will rust in 2-3 years in a humid environment, while the life of 304 stainless steel screws can reach 15-20 years.
3. EPDM waterproof gasket, 10-year sealing guarantee
Material performance:
EPDM rubber (ethylene propylene diene monomer) gasket, temperature range -40℃ to +120℃, anti-ultraviolet aging.
Compression rate ≥70%, ensure complete sealing after locking, pass IP68 waterproof test (static water pressure 1 meter/24 hours without leakage).
Life comparison:
Ordinary rubber gaskets will crack in 2-3 years, and the life of EPDM gaskets will be ≥10 years (verified by laboratory accelerated aging test).
4. High strength wind pressure resistance, torque value of 8-10Nm
Structural design:
Double thread (Type 17/Type 25) design to improve tapping speed and bite force.
Hex Washer Head increases the contact surface to prevent slipping.
Mechanical properties:
Tensile strength: 304 stainless steel ≥700MPa, carbon steel galvanized ≥500MPa.
Recommended torque range: 6-10Nm (compatible with mainstream power tools such as Bosch GSR 12V-35).
Application Suggestions And Installation Guide
Choose the right screw size: Choose a self-drilling screw of the right length and diameter according to the thickness and type of roofing material.
Mark the installation location: Mark according to the installation drawing or the required location.
Use power tools: Insert the screw into the power tool and install it directly at the marked position. The screw will automatically drill into the metal plate.
Tighten the screw: Make sure the screw is fully tightened and the rubber gasket is compacted to ensure waterproof effect.

Choosing galvanized or coated self-drilling screws can effectively prevent corrosion. Make sure that the screws are tightened and matched with rubber washers during installation to form an effective seal to prevent moisture from penetrating.
Selecting screws with high-quality anti-corrosion coatings (such as galvanizing or coating anti-corrosion) and ensuring the sealing of the screws during installation can effectively reduce the risk of rust.
