Cover and base fasteners 602, 604 may include one or more of nuts, screws, or any other mechanical closure. For instance, cover and base fasteners 602, 604 may each include a nut threadably receivable on sections 504, 512 (FIG. 5) of the stud 500 to compress first and second gaskets 131, 141. For example, fasteners 602, 604 may apply pressure to first and second gaskets 131, 141, respectively, when secured to stud 500. The pressure may compress first gasket 131 between housing base 114 and base fastener 604 and second gasket 141 between housing cover 116 and cover fastener 602. Stud 500, gaskets 131, 141, fasteners 602, 604, and input and output ports 115, 117 (FIG. 3A-B) of housing 112 can have one or more features to receive and secure stud 500 to one or more other portions of current monitoring module 110, such as housing base 114, housing cover 116, and/or PCB 132. The one or more features can include slots, channels, flanges, holes, threads, clips, or the like to connect and create an environmental seal between the ports 115, 117 and stud 500.
