Abstract
The present invention is for a method of fastening a tool holder. The tool (2) has a front side (6) shaped for use in cold forming of metal wire into nails, screws, etc. The tool holder (4) has a recess (8) shaped for receiving the tool (2). When the tool (2) is fastened in the tool holder (4), compressive stresses are initially present in the tool (2). The tool (2) is subjected to tensile stresses caused by the nail making process when in the tool holder (4). In order to reduce the resulting tensile stresses, the two opposite and wedge-shaped sides (10, 12) of the tool (2) are compressed against corresponding sides (14, 16) in the recess (8) by applying and maintaining pressure on the back side (18) of the tool with fastening means (20).
