Overview

GRK RSS Rugged Structural Screw has a patented design and made of especially 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 in. 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.

Questions & Answers

Can you use these for securing aluminum posts to a deck?

Can you use these for securing aluminum posts to a deck?
Asked by: Jerry
Most likely, NO. Galvanic reaction is the problem. GRK screws are coated and plated, but I wouldn't bet on them not reacting with the aluminum at some point in the future. It only takes a small nick in the coating to get the galvanic reaction going. The manufacturer could probably give you the best answer there. GRK are my favorite go-to fasteners, but as with all things, they have their limitations. The best answer is use the same metal. I.e., aluminum screws. Assuming that you cannot find or obtain aluminum screws or they do not meet strength requirements, the next best bet is a galvanized steel screw with a thick coating. Steel screws will rust and Stainless steel screws are a poor choice also as both are very reactive with aluminum.
