Stainless Steel Hex Head Shoulder Screws

Create the tightest hold with screws that also won't rust. The hex head generates more torque than you could with a socket head. Make sure there's room to fasten with a wrench or socket driver, as the drive is on the outside.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
