These sturdy nylon stand-offs are very handy for mounting a brushless motor in front of a firewall.
We like to use these 3/8" outside diameter stand-offs on brushless motors weighing up to about 3.5 ounces (480 class motors). For larger brushless motors, we recommend using 1/2" outside diameter nylon stand-offs.
Stand-offs dimensions: 3/8" outside diameter x 0.140" inside diameter (#6 screw).
Set includes four of each length stand-off: 1 inch, 1/2 inch, 1/4 inch.
Use with our #6 x 2.5" Machine Screws and Blind Nuts to mount a motor up to 1 3/4 inch out from a firewall.
