Abstract
A power impact device, particularly for fasteners, comprises a propelling passage, a driver movable in the propelling passage, a magazine for fasteners and crossing the propelling passage, and an abutment arranged for positioning a set of fasteners for separating a frontmost fastener by the driver, the abutment being formed so that only a part of the cross-section of the set of fasteners is supported and so that it is displaceable relative to the propelling passage, the driver having a cross-section which deviates from a cross-section of the propelling passage over a fit tolerance so as to allow narrowing of the propelling passage without preventing movement of the driver and reducing its thickness.
