Contact Surface Radii
Figures 4-16, 4-17, 4-18, and Table 4-5 show recommended radii of hoisting
tool contact surfaces. These recommendations cover hoisting tools used in
drilling, and tubing hooks, but all other workover tools. Contact radii are
intended to cover only points of contact between two elements and are not
intended to define other physical dimensions of the connecting parts.
