Fastening system including a screw component (10) and a seating component (20). The screw component has a shaft (12) extending along a longitudinal axis (5) and having a maximum radius R.sub.1, said shaft comprising a threaded section (13), said screw component further including, at one end of the screw shaft, a head (14), the head comprising a bottom end (15) having a larger maximum radius R.sub.2 than the screw shaft such that an exposed underside (18) of the screw head extends radially beyond the maximum radius of the screw shaft. The seating component includes a screw channel (21) having a planar screw seat (22) having a minimum radius R.sub.3 which is equal to or greater than R.sub.1. The bottom end of the screw head has an annular contact surface for abutment against said screw seat, the contact surface being formed by the distal end of at least one downwardly extending protrusion (17) on the underside of the screw head, wherein the annular contact surface has a minimum radius greater than the minimum radius of the screw seat.

A screw includes a screw head, a threaded shaft, and a force release component connecting the screw head to the threaded shaft. The force release component releases the screw head from the threaded shaft in response to a specified force. The specified force is substantially along a screw axis in-line with the threaded shaft.

A breakaway threaded fastener is provided. The fastener has a stud, a pin, and a cap. The stud has a hollow cavity with a closed end, an open end, a wall, and an outer surface. The outer surface has an external thread. The pin is in the hollow cavity. The pin has a first end at the closed end of the stud and a second end extending above the open end of the stud. The cap has another hollow cavity with a closed end, an open end, and an internal thread. The cap is threadably engaged to the open end of the stud via the internal and external threads so that the second end of the pin abuts the closed end of the cap.

A breakaway threaded fastener is provided that includes a hollow stud, a pin, and a cap. The stud has a hollow cavity, a closed end, an open end with an upper surface, a wall, and an outer surface, which includes an external thread. The pin is in the hollow cavity with a first end at the closed end of the hollow stud and a second end proximate the open end of the hollow stud. The cap has another hollow cavity with a closed end, an open end, an inner surface, and an internal thread. The cap is threadably engaged to the open end of the hollow stud via the internal and external threads so that the second end of the pin abuts the inner surface of the cap with a gap remaining between the upper surface of the hollow stud and the inner surface of the cap.
