PHEINOX 305 Stainless Steel screws are corrosion andstain resistant fasteners designed to withstand wetenvironments. PHEINOX 316 Stainless Steel screws aredesigned for coastal applications. GRKs patented R4,RSS, FIN/TRIM and RT composite screws are available inPHEINOX stainless steel.

GRK recommends PHEINOX 305 stainless steels screwsfor applications that require superior corrosion resistance inwet environments such as decks, boardwalks, pools, and hottubs. PHEINOX 305 stainless is also recommended for usewith cedar, red-wood and various other wood substratesthat have higher acid content as well as for composite
deck boards. PHEINOX 305 stainless steels screws arerecommended for applications located more than 1 milefrom the coast.

PHEINOX 316 stainless steels screws are recommendedfor applications exposed to salt water or located within 1 mileof the salt water shoreline.

The Zip-Tip feature of the screw allows a faster start andeliminates the need for pre-drilling. Hardened stainless steelprovides superior strength and unmatched performance bymaximizing torque and increasing bending yield.
