Our most popular hex head screws. These have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.
High-Strength Fastener—Commonly used to fasten components in valves, pumps, motors, and other high-stress applications. These screws have a tensile strength of 125,000 to 160,000 psi.
Steel — Unfinished steel screws are best for dry environments, since moisture will cause them to rust. They require little surface prep before applying a finish, so you can apply your own paint or coating.
