ISO 8764-1:2004规定了十字槽螺钉用手动驱动器和机器操作钻头尖端的形状和尺寸、技术要求和扭矩试验方法。它指定了两种形式的驱动器提示:H型凹槽的形式PH和Z型凹槽的形式PZ。（ISO 4757中规定了H和Z形凹槽，而ISO 8764-2中给出了手动螺丝刀的一般要求、刀片长度和标记。）

ISO 8764-1:2004 specifies the shapes and dimensions, technical requirements and torque test methods for the tips of hand drivers and of machine-operated bits for cross-recessed head screws. It specifies two forms of driver tips: form PH for form H recesses and form PZ for form Z recesses. (H and Z form recesses are specified in ISO 4757, while general requirements, lengths of blades and marking of hand-operated screwdrivers are given in ISO 8764-2.)
