Abstract
Torque limiting bolt employs a number pins which shear upon the application of a predetermined torque to the bolt head. The bolt configuration insures that sheared portions of the pins are held within the bolt head to prevent undesirable scattering of the pin portions on an airstrip. A removal hex head is thinner than a driving hex head positioned over the removal hex to discourage the application of a wrench directly to the removal head. The outermost portions of the hex heads are also angularly displaced from each other for this purpose.
