1) The size in parentheses should be avoided if possible. 2) P pitch of the thread. 3) For lengths l_nom 125 mm. 4) For lengths 125 mm < l_nom < 200 mm. 5) For lengths l_nom > 200 mm. 6) Radius r₂ applies both at the corners and at the flats of the hexagon. 7) Screws with lengths shown above the continuous thick line are threaded to head. 8) Reduced shank type (type R) only below the dashed thick line. 9) l_g is the minimum grip length. NOTE If the product passes the gauging in annex A, the requirements for dimensions e and k' are satisfied.
