- As far as it is possible, it is recommended to avoid embedding a hole in the body of the screw or another mechanism is utilized for rotation and bolt tightening, like press-fitting of the pin in the hole, to prohibit stress concentration in the screw.
- A fillet is created under the screw head to decrease the stress concentration in this location.
- In case of a fillet generation under the screw head as mentioned above, in the corresponding location over the internal surface of conical piece hole, an appropriate bevel is created to assure a complete contact between the lower surface of the screw head and the internal surface of the conical piece hole and stress concentration is decreased, simultaneously.
