The ball tip lets you engage a socket-head cap screw at an angle - up to around 25 degrees off-axis - so you c an reach fasteners buried behind the gantry, in extrusion channels, or under the toolhead where a straight key simply won't line up.The plain end of each key gives full torque for final tightening. A core tool for Voron and other CoreXY builds, where bolts are often tucked into awkward corners. Metric sizes. Show more
