The terminal system consists of tabs (male) and receptacles (female). There are free-hanging wire and circuit board mounted versions of both tabs and receptacles. All widths come mostly in one of two tab thicknesses: 0.032 and 0.020 in (0.8 and 0.5 mm). A hand tool exists for inserting the terminals: the AMP Universal Handle. [citation needed]
