These 2" (51mm) long case hardened stainless deck screws were specifically designed for use with 19mm (3/4") and 29mm (1-1/8") decking material, and work great with the Kreg Deck Jig™. The Stainless screws provide the ultimate in rust and corrosion-resistance in the long term. They’re uniquely designed to stand up to indirect maritime applications and other exceedingly-corrosive environments. The Flat-bottom head helps to prevent workpiece splitting.
