When mounting the ZEUS use only M3 (metric) or 4-40 (Imperial) screws. The
mounting pad is 6.35mm (0.25") and the hole is 3.175mm (0.125"), so ensure
any washers fitted are smaller than the pad.
Using oversized screws and washers, or tooth locking washers, can cause
short circuits and over-voltage conditions.
We recommend that you use a Loctite screw thread lock or a similar product
over tooth locking washers.
