- Hex Head Airframe Bolts come in either drilled or undrilled shank versions
- Threads are pressed into the steel, not cut, thus maintaining strength throughout the entire shank
- The surface under the head of AN bolts is designed to be a bearing surface to reduce non-uniform stress as the bolt is torqued thus reducing premature fatigue
