What are the specifications of the GRK12225 deck screw?

The GRK12225 deck screw has a screw size of 5/16 in, length of 4 in, and a T30 Torx®/Star drive. It is made of steel with a Climatek™ coating, features a round head and partially threaded thread style, and comes in a 100-pack. The manufacturer part number is GRK12225.

Where to buy GRK deck screws in worldwide?

How to install GRK 5/16 in deck screws?

Pre-drill a pilot hole slightly smaller than the screw shank to prevent splitting. Use a T30 Torx®/Star bit at low to medium torque to drive the screw flush with the wood surface. For exterior decks, ensure the Climatek™ coating remains intact; avoid over-torquing to maintain thread grip in treated lumber.
