MSR Coupling Mounting Screw Kit
A set of ten (10) small replacement screws for use when mounting the shaft to the MSR motor coupling.
Note that these screws have a “hex head” which allows an Allen wrench or hex driver (included) to be used to securely tighten the screws.
Early MSR rotators used a flat head screw type. The Allen screws may be used to replace the flat head screws on these earlier rotators.
