Why we recommend it
The assortment that ends "I’m one screw short". Hex brass male-female standoffs in M2 through M4 let you mount the Arduino, PCA9685 and power module cleanly off the frame — lifting solder joints away from metal so nothing shorts. The kit includes matching screws and nuts, covering essentially every board and bracket on a hobby arm. Brass means it won’t strip like cheap nylon under repeated assembly.
