GRK Fasteners PHEINOX™ 305 Stainless Steel screws #8 x 3-1/8” (#8 x 3-1/8”)

PHEINOX™ 305 Stainless Steel screws are corrosion and stain resistant fasteners designed to withstand wet environments. PHEINOX™ 316 Stainless Steel screws are designed for coastal applications. GRK’s patented R4, RSS, FIN/TRIM and RT composite screws are available in PHEINOX™ stainless steel.

GRK recommends PHEINOX™ 305 stainless steels screws for applications that require superior corrosion resistance in wet environments such as decks, boardwalks, pools, and hot tubs. PHEINOX™ 305 stainless is also recommended for use with cedar, red-wood and various other wood substrates that have higher acid content as well as for composite
deck boards. PHEINOX™ 305 stainless steels screws are recommended for applications located more than 1 mile from the coast.

PHEINOX™ 316 stainless steels screws are recommended for applications exposed to salt water or located within 1 mile of the salt water shoreline.

The Zip-Tip™ feature of the screw allows a faster start and eliminates the need for pre-drilling. Hardened stainless steel provides superior strength and unmatched performance by maximizing torque and increasing bending yield.
