A fastening system for setting stump type swage fasteners providing high fastener clamping force and low application loads and low removal loads of the associated tool; the associated tool anvil, comprising self releasing anvil segments, has a swage surface providing desired material flow to enhance fastener clamping force and also has relief grooves which inhibit galling and result in 'witness' lines providing a visual indication of proper setting of the fastener. |
