GRK Fasteners 95400 5/16 in. x 3-1/8 in. Star Drive Low Profile Washer Head Structural Wood Screw (100-Pack)
GRK RSS Rugged Structural Screw has a patented design and made of specially hardened steel to provide customers with high tensile, torque and shear strength. The sharp threads and points bite instantly into material, including hardwood, reducing the splitting effect due to smaller shanks. The GRK RSS series screws that are 3-1/8 in. and longer have 6 CEE threads which enlarge the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily and increases the screw’s drawing strength.
- Easy to install lag alternative
- Ideal for carrying beam, playground equipment, ledger board, deck posts and stair rails
- Made of extremely high quality carbon steel that provides high tensile torque and shear strength
- Patented climatek coating for all weather corrosion protection
