It is code listed in IAPMO UES ER-192 and meets 2018 and 2021 IRC® and IBC® code requirements for most common wood framing applications.Key Features

- Under-head nibs offer greater control when seating the head
- Large low-profile washer head provides maximum bearing area (3/4 in head Dia)
- Size identification on all SDWS screw heads
