GRK Fasteners 5/16 in. x 6 in. Star Drive Bugle Head Pheinox 30 5 SS RSS Structural Alternative Lag Screws (300-Pack)

GRK's PHEINOX RSS screw is made of PHEINOX hardened Stainless Steel. Its sharp threads and point bite instantly into material (including hardwood), reducing the splitting effect caused by smaller shanks. Its washer type head has no sharp edges like conventional lag screws and the added shoulder underneath the washer has the ability to center the RSS screw in pre-drilled hardware.

• GRK rugged structural screws (RSS) are a lag screw alternative
• RSS screws with integrated washer head for max clamping force
• GRK rugged structural screws (RSS) for interior and exterior use
