ABSTRACT:
A torque limiting set screw is disclosed with a driving head at one end and a seating head at the other end. The driving head is connected with a threaded shank by a torque control neck. The seating head comprises a disk having a seating surface with a point extending from the surface for indentation into a member to be retained. The seating surface is of larger area than the cross-sectional area of the shank and is adapted to seat against the member after the point is fully indented. The large area surface engagement by the seating head distributes the force of the set screw on the member and prevents damage to the member.
