Abstract
A symmetric clamp structure having a first arm and a second arm. Both the first arm and the second arm having coaxial threaded bores through the distal ends of each arm. The symmetric clamp structure also includes a screw having a shank, the shank having a head at one end and being threaded at a second opposite end. The threaded portion of the shank is sized and has a pitch appropriate for threadably engaging the screw with the threaded bores through the distal end of both the first and second arm of the clamp structure. The shank of the screw also has a clearance portion between the threaded portion and the head. The screw is threadably engaged with one of the first or second threaded bores such that the head abuts the arm opposite the threaded engagement. The clearance portion has an outer diameter sized to clear the tips of the threads of the threaded bores and a length at least equal to the axial length of each threaded bore. Preferably the axial length of the clearance portion exceeds the axial length of each threaded bore.
