A different method of removing axial backlash consists of utilizing a spacer between two nut halves that are fastened along with bolts.
The sloped, bugle shape of drywall anchor screws causes it to be straightforward to countersink them in drywall without harming the panels.
The screw shaft is rotated by a stepper motor With all the aid of the beam coupling. The rotation with the screw shaft engages the linear motion in the nut alongside the size from the screw shaft. The beam coupling accommodates the misalignments that could come about all through higher-pace motion.
