Copper alloy screw. A screw with threaded shank and a flat head now canted against the top of the shank; tip lost. The distortion and flattening of the shank may suggest mechanical force was involved in its deliberate modification, albeit this would seem to prevent the object fulfilling its function. Suggested date: Post-Medieval, 1800-1900
