Dubro 3.17mm Collet for 1-9/16 Electric Tool - DUB981

The Dubro DUB981 collet is a 3.17mm shaft collet designed to secure propellers and spinners to electric motor shafts on RC aircraft. Sized specifically for 1-9/16 inch electric motor applications, it provides a reliable mechanical connection between the motor shaft and prop driver without requiring a threaded prop adapter.
