GRK Fasteners

screw rss mini 5/16x4in - Description

GRK’s RSSscrew 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 that are 3-1/8” and longer have 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 result in lowering the driving torque and the likelihood of splitting the wood. This is why the RSSscrew 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. Zip-Tip - Eliminates predrilling and one step installationUnique Thread Design & Washer Style Head- Unique thread design draws two substrates together while washer head allows zero gap jointsW-Cut - Low installation torque allows for fast driving and ease of installCEE Thread -Enlarges hole to reduce splitting, thus eliminating reworkESR-2442 Approved-Approved for structural applications
