Product Advantages

Double Thread Design for Exterior Roofing Applications Optimized double thread structure balances drilling efficiency and fastening stability, ideal for long-term outdoor roofing and construction applications.	High Thread Under Head Prevents Strip-Out The high thread under the screw head provides stronger panel engagement, reducing slippage and stripping during installation.
Continuous Thread for Superior Pullout Resistance Thread design extending from the drill point to the shank maximizes pullout resistance and minimizes loosening over time.	Enhanced Locking Performance for Heavy-Duty Projects Heat-treated carbon steel construction delivers strong locking, anti-loosening, and vibration resistance for demanding steel structure applications.
