Abstract
An arbor system includes an arbor, a clamp body of a power tool, a tightening feature and an optional snap feature. The arbor has a flanging feature, a thread and a number of circumferentially arranged driving pins. The clamp body is sandwiched between the arbor and tightening feature in a pressed contact with the flanging feature defining a releasable fix that is fully form fitting. Operational tilt and load torque are transmitted without affecting the tight-screwed interlocking between thread and tightening feature. A snap feature, in the form of a spring pin or a spring tongue of a sandwiched washer, may secure the tightening feature against inadvertent unscrewing. The snap feature and snap serrations may be configured as a ratchet such that the snap feature needs only be actuated during unscrewing of the tightening feature.
