GRK's RSS screw is made out of Climate coated and hardened 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 predrilled hardware.
- Ideal for ledger boards and more
- W-cut thread design
- May be used as a lag screw alternative
- Washer heads for flush installation
