H. PAULIN & CO LIMITED 537-308 8 x 2" Flat Head Square Drive Deck Screw - Brown Duradized II-ACQ Approved - UNC

DECK SCREWS are formulated to prevent rust, staining, or streaking in chemically treated wood including ACQ. Duradized screws may not perform due to weather and surface breaches on wood not properly treated and sealed. The reinforced neck provides for increased driving torque. Screw threads include a cutting feature. This revolutionary "Sawtooth" thread requires less driving torque and outperforms traditional Type 17 thread cutting screws. This screw reduces splitting and results in greater holding power.
