Review on ABN Piece Ball Joint Kit by Anthony Mcgarry

The threaded part uses a 60* thread form rather than the much heavier trapezoidal design used in the G-clamp or vise, resulting in thread galling when force is applied. In addition, the clamping surfaces are not parallel, which prevents uniform pressure on the workpiece, resulting in the ball joint bushing being stuck in the control lever seat by the oblique pressure.
