With a low-profile, countersunk head, flat head socket cap screws are ideal for applications requiring a strong fastener with a flush mount. They are often used in projects what require moving parts to pass over a fastened area. Because of their ability to mount flush with the surface, they are less apt to snag objects moving overhead. Use an allen wrench (hex key) for installation and removal.
