5/16 in. x 5 -1/8 in. Star Drive Low Profile Washer Head RSS Structural Screws (300-Pack)

GRK RSS Rugged Structural Screw has a patented design and made of especially 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.”,”highlights”:[“Easy to install lag screw alternative”,”Integrated washer head allows for maximum clamping force”,”Stainless Steel for superior Corrosion Resistance”
