The Bohning H.E. Nocks are a small, press fit nock designed to work with "D" loops. These use a double lock feature that holds the nock on just tight enough to hold your shaft firmly on the string but maintains a clean release for every shot. The H.E. nocks have an outside diameter of 0.231" making them similar to the "H" nock size.
Outside Diameter: 0.231"
Fits: Easton Hexx, Easton Bloodline, Easton Wild Thing, Easton Caron Aftermath, Easton Ion
