Pan American Screw, LLC.

Square Drive Rustguard^® provides maximum protection against rust and corrosion. They feature a self-drilling Type-17 point to eliminate splitting in most types of wood and man-made materials and self-countersinking nibs for a faster finished look. Our Square Drive Rustguard^® Decking Bullets^® feature the original Robertson^® square drive recess that eliminates driver bit slippage and greatly reduces bit wear. The combination of our self-drilling features in conjunction with our Robertson^® square drive recess makes these fasteners THE ULTIMATE DECK SCREW. We outperform star drive screws in drive torque every day! The Rustguard^® coating is a dull gray color that blends with most pressure treated lumber and many man-made decking materials. These fasteners have been successfully tested to exceed a 1500 hour salt spray test (ASTM B117) and achieve 20 Kesternich cycles (DIN 50018). Made of case hardened 1018 steel, they offer exceptional strength and unequaled holding power. Rustguard^® Decking Bullets^® feature a deep #2 Square recess that is virtually unaffected by the heavy-duty coating we use thus providing optimum driving torque between driver bit and fastener.
