Nut - Dress Nut, Threaded Through, For Mini Toggle Switches
Threaded through dress nuts for use with mini toggle switches. Unlike the other versions of this dress nut, this nut is not capped allowing the nut to thread past the top of the switch’s bushing. The uncapped top can be useful where internal depth is an issue such as parallel PCB mounting. These plated dress nuts feature a chamfered edge for a professional look and work on any 1/4-40 UNS threaded bushing. Two sides are flatted for use with a tool when fastening.
