M2-0.40 x 4mm Socket Head Screws (8pcs)

- These are socket head screws for mounting the 22mm 730rpm Premium Planetary Gear Motor and Mega Spark Gearmotors to our older Flat Motor Mounts.

- Black Oxide screws are harder than Stainless Steel or Zinc Plated and the heads will not strip out or break as easily. 

- Includes 8 screws, good for mounting two motors.

- Weight per screw: 0.2g

- Requires 1/16in hex wrench (technically a 1.5mm hex wrench, but 1/16in is 1.5875mm, so it usually fits!)
