Abstract: The fastener tool includes a nosepiece, a nosepiece cover pivotally attached to the nosepiece, a latch pivotally attached to the nosepiece cover, a latch wire pivotally attached to the latch for engaging at least one hook disposed on the nosepiece, wherein the latch wire has a portion extending between the latch and the hook, the portion having at least two bends.

Abstract: A fastening tool including a housing, a magazine connected to the housing for storing a fastener, a driving mechanism disposed within the housing for driving the fastener into a workpiece, a trigger assembly pivotally attached to the housing for activating the driving mechanism, the trigger assembly comprising a main trigger, pivotally attached to the housing and a supplemental trigger pivotally attached to the main trigger; and a contact trip assembly comprising an upper contact trip contacting the supplemental trigger, a lower contact trip connected to the upper contact trip, wherein the upper and lower contact trips have teeth that mesh together for locking the upper and lower contact trips.

Abstract: A production assembly tool for securing fasteners to a workpiece such as an automobile body. The production assembly tool of the present invention includes a housing which encases a motor, a transmission, a clutch mechanism and a control module. The control module controls the running and braking of the motor and prevents both over and under securing of a fastener caused by falsely detected tool clutch conditions. An improved clutch sensor switch is operatively associated with the control module for detecting clutch disengagement. The clutch mechanism is designed to drive the fastener until the clutch sensor switch detects clutch disengagement and signals the control circuit to stop drive and start braking. The production assembly tool further includes a system for ensuring accurate placement of the power tool motor in the power tool housing subsequent to motor servicing or repair.
