ISO DIS 10642

Description / Abstract: This International Standard specifies the characteristics of hexagon socket countersunk head screws with reduced loadability due to head design, in steel and stainless steel, with metric coarse pitch threads M2 to M20, and with product grade A.

NOTE The reduced loadability (related to the countersunk head dimensions in combination with penetration of the hexagon socket specified in this standard) implies a limitation of ultimate tensile load, see Table 3.
