GRK RSS Rugged Structural Screws
GRKs RSS™ Rugged Structural Screw is hardened steel to provide maximum tensile and shear strength.
The RSS™ screw is the only lag screw replacement of its kind. These are the perfect choice where strength and holding power are essential
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" 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 screws drawing strength. This also reduces the likelihood of splitting the wood as well as lowering the required driving torque.
GRK RSS™ screws feature around head with built-in shield (washer type head) has no sharp edges, unlike 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.
The #30 Star Drive will deliver approximately 650 foot-pounds of torque, eliminating the need to drill a pilot hole. A driver bit is included in each Handy Pack of screws.
Note: Different sizes and quantities are available by special order. Some sizes are also available in Stainless Steel.
