It is no. 0 (0.060 in.) (1.5 mm) or larger, and is designed to be held or driven with either a wrench or inserted driver (excluding internal socket and multiple spline types) or both in sizes below no. 10 (0.190 in.) (5 mm) and larger sizes must have a head designed for any type inserted driver (excluding internal socket and multiple spline types) but may also be designed for external wrenching. A locking feature may be incorporated in the design of the head or threads. See also bolt, externally relieved body and bolt, internal wrenching.
