M5 Bolt-Shank Drill Wire Twister
This is a 60 mm wire-twisting plate for a cordless drill. It uses an ordinary M5 hex-head bolt (8 mm across flats) as its shank: the bolt head sits in a hex pocket in the face, and a nut on top clamps it against a 16 mm hub. You chuck the shank in the drill, hook two or three wires into the V-notches or 3.2 mm tie holes, and twist a neat pair or triple for motor leads, audio runs or antenna feeds.
