Flat Socket Cap

Flat socket cap screws are the go-to choice when you need a secure hold with a clean, flush finish. At South Coast Fasteners, Inc., we carry a full selection designed for tight installs, smooth surfaces, and solid performance. These are the fasteners engineers, fabricators, and manufacturers turn to when exposed heads aren’t an option.

With an internal hex drive and a countersunk head, flat socket cap screws sit flush with the surface. That makes them ideal for applications where low-profile hardware isn’t just a preference, it’s a requirement. Whether you're building electronics, assembling machinery, or finishing structural panels, these screws provide reliable strength without standing out.
