These light-weight brackets are specifically designed for Pololu’s 37D mm metal gearmotors. Each bracket features fourteen mounting holes (seven along each edge) for M3 or #4-size screws, giving you a variety of mounting options. A total of twelve 5 mm M3 screws (six for each bracket) are included for securing the motors to the brackets.
We also carry a machined bracket for our 37D mm gearmotors that provides an alternate, sturdier mounting option (this stamped L-bracket can bend under heavy load).
