ABSTRACT:
In a ball head lock nut as a component element of bicycle head parts, a split clamping ring is received within an annular groove formed in a threaded, cylindrical internal wall of a substantially annular nut body; a deformable fixing piece, which has a diametrically extending slot formed in its inner end wall, is disposed within a radially extending threaded through hole formed in the annular nut body, with the slot engaged with a part of the split clamping ring; and a set screw is screwed into the radially extending threaded through hole to push the deformable fixing piece axially inwardly for forcible compression and deformation.
