This Document specifies the type, dimensions, technical conditions, marking, labels and signs of hexagon socket countersunk head screws with reduced loadability due to head design. This Document is applicable to hexagon socket countersunk head screws with thread specifications M2~M20; coarse threads; performance levels 8.8, 10.9 and 12.9; groups and performance levels A2-50, A4-50, A2-70, A4-70, A2-80 and A4-80, and Level-A products. NOTE 1: For other size options, see GB/T 2, GB/T 197 and GB/T 3106. NOTE 2: Reduced loadability (related to the combination of countersunk head size and hexagonal penetration depth specified in this Document) implies a limit to the minimum tensile load (see Table 5). NOTE 3: Special attention needs to be paid to ensure that the countersunk head is aligned with the countersunk hole support surface in the assembly.
