A hot stick device may include a tool connector having a connector body with a proximal end coupled to a distal end of an insulated shaft, a distal end, and first and second opposing longitudinal sides extending between the proximal end and the distal end. The first longitudinal side of the connector body may include a first interlocking interface. The tool connector may have a fastener having a head, and a threaded shaft extending in a through passageway, a first threaded nut threadingly engaging the threaded shaft, and a spring device coupled between the head and the second longitudinal side. The hot stick device may include an accessory tool with a second interlocking interface to engage with the first interlocking interface and coupled between the first threaded nut and the connector body.
