These standards from ISO and SAE cover standardized screw socket requirements sorted by head. This list covers hexobular socket screw standards.
ISO 10664:2014 specifies the shape and basic dimensions of the hexalobular internal driving feature for bolts and screws, including the gauging method. The curvature of the contour of the hexalobular internal driving feature is defined and additional information which can be used when drawing the contour given. The intent is to provide the details necessary for inspection of the hexalobular driving feature. ISO 10664:2014 is not suitable for, nor intended to be used as, a manufacturing standard.
ISO 14579:2011 specifies the characteristics of hexalobular socket head cap screws, with thread sizes from M2 up to and including M20, of product grade A.
ISO 14580:2011 specifies the characteristics of hexalobular socket cheese head screws of product grade A and with thread sizes from M2 up to and including M10.
ISO 14583:2011 specifies the characteristics of hexalobular socket pan head screws of product grade A and with thread sizes from M2 up to and including M10.
ISO 14584:2011 specifies the characteristics of hexalobular socket raised countersunk head screws of product grade A, and with thread sizes from M2 up to and including M10.
ISO 14585:2011 specifies the characteristics of hexalobular socket pan head tapping screws with thread sizes from ST2,9 to ST6,3 inclusive. If, in special cases, specifications other than those listed in ISO 14585:2011 are required, they can be selected from existing International Standards, for example ISO 1478, ISO 2702, ISO 4759-1.
ISO 14586:2011 specifies the characteristics of hexalobular socket countersunk head tapping screws with thread sizes from ST2,9 to ST6,3 inclusive. If, in special cases, specifications other than those listed in ISO 14586:2011 are required, they can be selected from existing International Standards, for example ISO 1478, ISO 2702, ISO 4759-1.
ISO 14587:2011 specifies the characteristics of hexalobular socket raised countersunk (oval) head tapping screws with thread sizes from ST2,9 to ST6,3 inclusive. If, in special cases, specifications other than those listed in ISO 14587:2011 are required, they can be selected from existing International Standards, for example ISO 1478, ISO 2702, ISO 4759-1.
