Abstract
A fastener system with a coaxial annular flange (14) having through holes (16), each serving to pass a screw (17) for screwing into an associated tapped hole (16) in the wall (2) of a stationary structure. Each through hole (16) has a circularly cylindrical distal segment (16a) followed by an enlarged proximal segment (16b) adjacent to the wall (2) of the stationary structure, allowing the shank (19) of the screw to bend and enabling a corresponding lateral offset (D). This prevents the screw (17) rupturing under high shear forces due to accidental destruction of a vacuum pump rotor while rotating at full speed.
