SCREW MULTI-PURPOSE 8X2IN SCREW MULTI-PURPOSE 9X1-3/4IN STRUCT SCREW RUG BLK 1/4X1-1/2
GRK Fasteners R4 Framing and Decking Screw, Multi-Purpose, Thread Size: #8, Thread Length: 1.299 in, 2 in L, Drive Type: Star, Drive Size: T-15, Steel, Applicable Materials: Cement, Fiber Board, Melamine, Particle Board, Plastic, Sheet Metal, Wood R4 Multi-purpose framing and decking screws provide a faster drive for improved productivity. GRK's RSS? screw is made of specially hardened steel to provide you with high tensile, torque and shear strength. The sharp threads and points bite instantly into the material (including hardwood), reducing the splitting effect due to smaller shanks. RSS? screws that are 3-1/8 in and longer have 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 result in lowering the driving torque and the likelihood of splitting the wood. This is why the RSS? screw is an efficient lag screw alternative. Our round head with built-in shield (washer type head) has no sharp edges like conventional lag screws. The added shoulder (nominal diameter) underneath the washer has the ability to center the RSS? screw in pre-drilled hardware like hinges and connector plates.

Multi-use screw for wood, particle board, sheet metal, cement fiber board, laminate and wood decking and melamine. They are self tapping eliminating pre-drilling featuring a countersinking head with cutting teeth, W-Cut? for reducing splitting, CEE Thread? for no splitting, reducing install torque and our Climatek? AC257 code approved coating. New in 2025: Black R4 featuring a black coating for aesthetic applications and finishes. GRK's R4? self-countersinking screw has a patented underhead with saw-blade like cutting teeth and six self-contained cutting pockets. Together they act similar to a circular saw-blade, transporting the drill dust away from the edge of the screw hole while cutting a ideally clean hole into even the most brittle materials without cracking any surface treatment. This design enhances the R4?'s versatility by allowing the fastener to countersink into even the hardest woods. The head of the screw closes the hole off with precision, leaving no damaged fibers around the head. R4? screws 2 in and longer have a four threaded CEE Thread. This enlarges the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily. It increases the screw's drawing strength and reduces the friction on the screw shank that lowers the driving torque.
