Flat Socket Head Cap Screws are ideal for applications in which there is not enough space to maneuver wrenches or sockets and have an internal-wrenching drive, such as a hex socket. Also known as socket head bolts. The flat head sits flush with the surface. Bare finish fasteners have very low corrosion resistance. This is a good choice for indoor use or when protection from the elements is not an issue.
- Ideal for use indoor environments where moisture is minimal
- Available with a coarse thread design, these come in options of either partially threaded (PT) or fully threaded (FT)
- Features a hexagon socket drive that requires Allen Keys or hex wrenches for installation or removal
