GRK's patented Rugged Structural Screws are made of specially hardened steel to provide high tensile, torque and shear strength. Sharp threads and points bite instantly into building materials (including hardwood) - reducing the splitting effect due to smaller shanks.
Featuring a round head with built-in shield (washer type head) which has no sharp edges such as on 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 unique design enables users to skip the pre-drilling, wrenching and pre-countersinking stages, thereby eliminating three of the four steps necessary when using ordinary lag screws. The RSS can considerably speed up the installation of the deck substructure and is ideal for constructing pergolas, landscape walls, newel posts etc.....
The revolutionary Climatek coating is featured exclusively on GRK products. With a gold coated appearance it is the only such plating which offers long life corrosion protection in exterior climates. Salt spray testing has exceeded 1,200 hours and 30 Kesternich cycles."
Climatek Gold matches nicely with virtually all woods and other surfaces. Eliminate unsightly green, gray or black screw heads without reducing your rust protection. GRK screws are almost indistinguishable from brass screws, once installed into a surface. This high class appearance will certainly add to the beauty of your project, whatever or wherever it may be.
The #30 Star Drive will deliver approximately 650 lbs of energy, eliminating the need to drill a pilot hole.
The RSS screw is the only lag screw replacement of its kind.
