These pins feature a larger shaft on the "near" end of the pin and a tapered run-out (TRO) feature at the thread-shaft junction to attenuate any potential stress riser, resulting in a pin with increased bending resistance and enhanced cyclic fatigue life compared to traditional positive-profile pins (Vet Comp Orthop Traumatol 2011; 4: 257-261).

These pins along with related drill bits and taps are designed for lower limb applications in large animal patients. Both pin sizes incorporate three chuck flats on the blunt end for securing the pin into a Jacobs chuck. Predrilling and tapping are required.
