GRK Pheinox RSS Rugged Structural Screw - 305 Stainless Steel. 5/16" x 4" (7 x 100). Condition: Brand new in non-factory bulk package.
See Attached Photo for Detailed Specs. 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. This GRK RSS series screw has six 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. The cee thread also reduces the friction on the screw shank which can lower the driving torque and reduce splitting. The round head with built-in washer type head shield does not have any sharp edges like conventional lag screws.The added shoulder underneath the washer has the ability to center the RSS screw in pre-drilled hardware like hinges and connector plates. The RSS screws can be used as a lag screw alternative. Recommended in tropical wood, cedar wood, pool, hot tub, sauna and sea-side applications, as well as deck applications in areas with large daily temperature variances. Uses T-30 Torx Bit (Not supplied).
