摘要： An installation head, fastener, and method for installing the fastener are disclosed. The installation head has control fingers which control the position of the fastener with respect to the plunger and workpiece to which the fastener is to be attached during the entire travel of the fastener from the entry into the installation head to installation in the workpiece. The fingers are pivotally mounted to the plunger and travel with the plunger throughout the installation path. The fingers are adapted to engage the fastener in a displaced area on the fastener so that the fingers can control the fastener through installation of the fastener into the workpiece. The displaced area is positioned between the top and bottom of the fastener so that the fingers can maintain control throughout installation.

摘要： An automatic screw clamping device for automatically tightening bolts fitted in a metallic mount member, which is hard to nail includes a casing (2), a rotator (4) disposed in the casing (2) in a manner that the rotator may rotate and move up and down, a biasing member (5) connected with the rotator (4) and the casing (2), and a covering member for covering over the casing (2). Fitments are provided on the lower end of the casing (2). The rotator (4) includes an inner periphery having an engaging portion (41) that can unrotatably mesh with the clamped member (n), and includes an outer periphery with a locking portion (42) which is unrotatably lockable to the casing (2). The rotator (4) locked to the casing (2) is engaged with the clamped member (n) to press the casing (2) downward. This may cause the casing (2) to be detached from the rotator (4), then the casing (2) turns and the fitments (71) enter into the corresponding fitment-receptive portions (82) of the washer member (8) disposed beneath the clamped member (n) until the casing (2) is fixed to the washer member (8), whereby the rotator (4) can be maintained in a position where the clamped member (n) is biased in a direction when being tightened.
