SCREW R4 STAR PPK 9X2-3/4IN   SCREW R4 STAR PPK NO10X4.314IN SCRW DCK COMBO 9X2-1/2 25LB
#6 and #8 screws use T-15 bit; #9, #10, and #12 use bit T-25. Self-tapping, countersinking head; W-Cut thread design. Climatek coated for all weather corrosion protection conforms with ICC#2442. For use in wood, particle-board, cement fiberboard, plastic, and sheet metal. 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 perfectly 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. Decking screws are used for decking and wood to wood construction. The PRO-FIT?? decking screws category includes ceramic coated deck screws with coarse threads for superior holding power when attaching to wood.
SCRW DCK COMBO 9X3 25LB       SCRW WD S-TAP STAR-DR 5/16X4IN SCREW RSS INDV 3/8X10IN
Decking screws are used for decking and wood to wood construction. The PRO-FIT?? decking screws category includes ceramic coated deck screws with coarse threads for superior holding power when attaching to wood. GRK's RSS??? rugged structural 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 which are 3-1/8 in and longer have a six threaded CEE thread that enlarges the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily and increasing 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.

SCREW MP FRME/DECK NO9X1-1/2IN SCREW MTL SIDING WH 9X1-1/2IN
GRK Fasteners R4 Framing and Decking Screw, Thread Size: #9, 1-1/2 in L, Drive Type: Star, Steel, Package Quantity: 5200 BX, Multi-Purpose, Thread Length: 1 in, Drive Size: T25, Applicable Materials: Cement Fiber Board, Melamine, Particle Board, Plastic, Sheet Metal, Wood The MSS? was developed and patented based on the RSS? model. This screws has an integrated washer-head and is complemented by a rubber washer below the screw head. This feature also helps protect the washer from prolonged exposure form the sun for long-lasting, secure siding applications. No pre-drilling is need due to the MSS? tip design for thin sidings as well as thick studs. The MSS? is powder-coated for exceptionally high corrosion resistance.
