GRK RSS10318-5 RSS ProPak 10 by 3-1/8-Inch Structural Screws, 236 Screws per Pail
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-Inch and longer have 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. Some sizes available is PHEINOX Stainless Steel.
GRK Cabinet screws have a patented design for specific use in cabinet construction and installation. Cabinet screws are manufactured in a #8 gauge (4mm) diameter. These screws are thin enough to prevent most material splitting. The washer head design presses flush against any material surface. Some builders even use the GRK Cabinet screws in vinyl siding installation.

GRK RT ProPak Trim Head Composite Deck Screws, 9 by 2-1/2-Inch, 408-Count
GRK RT Composite TRIM Head Screws have the smallest screw head available and work great for most fine carpentry applications. Most material splitting is prevented because of the TRIM Head screw's exceptionally small head and the W-Cut thread design. The RT screws include a reverse threading under the head of the fastener. GRK has found that the reverse thread helps the screw head disappear beneath the surface of the classic wood composite material, reducing or eliminating the dimple that sometimes appears. Some sizes are available in PHEINOX Stainless Steel.
