Abstract
An example whipstock assembly includes a whipstock providing a ramped surface and a longitudinal groove defined in the ramped surface. A lead mill is coupled to the whipstock with a shear fastener that provides resilience against premature shearing under torsional loads between the lead mill and the whipstock, while providing susceptibility to shearing under a predetermined axial load.
