PL-259 And BNC Double V-Jaw Coax Wrench
This is a flat 153 mm double-ended wrench with a 60° V-jaw at each end. The large jaw is 28 mm wide at the mouth and wedges round or hex coupling nuts from about 10 to 26 mm, which covers PL-259/SO-239 and N connectors. The small jaw is 16 mm wide and takes about 5–14 mm, for BNC, SMA and F connectors. Because the V grips by wedging, no exact nut size is needed. You can snug and loosen coax at an antenna or radio without crushing the knurl with pliers. It prints flat, 8 mm thick, so the turning load runs along the layers, and it has a 5.5 mm hole for hanging it on a peg.
