Abstract
Abstract A method and means for drivingly coupling apertured parts such as pulleys, gears and wheels to a shaft. The hub of an apertured part is provided with a radially extending hole. A pointed hardened pin is positioned in the hole with its pointed end engaging the shaft and with its opposite end extending radially outwardly of the hub. A clamping band is crimped in place around the hub so as to force the pin radially inwardly thereby driving the pointed end of the pin into the shaft.
