A torque limiting fastener includes a fastener body and a fastener head insert configured to fit within the fastener body and to transfer a limited amount of torque to the body. The fastener body has a head with a bore formed therein and having a first set of protrusions. The fastener head insert has a tool interface for accepting a mounting tool and a perimeter edge onto which a second set of protrusions are disposed. A torque applied to the tool interface region will rotate the fastener head insert within the bore and cause the second set of protrusions to engage with the first set of protrusions to transfer torque to the fastener body. If the applied torque exceeds a limiting value, the second set of protrusions will fail to maintain engagement with the first set of protrusions and the fastener head insert will rotate without transferring the excessive torque.
