  • Attachment member setting tool and method of setting the attachment member
    Patent number: 5833420
    Abstract: Attachment members (28) are used for securing insulation panels (30) to structural components (31). Each attachment member (28) includes a nail (29) which is driven by a setting tool into the structural component. A connecting region (26a) on guide tube (25) of the setting tool generates a frictional force with a counter-connecting region of a hollow shaft (28b) in the attachment member when the nail (29 is driven. By means of the generated frictional force it is possible to check if the attachment member is properly connected after the setting tool drives the nail. The frictional force between the guide tube (25) and the inside surface of the hollow shaft is greater than the frictional force between the hollow shaft (28b) and the insulation panel (30).
    Type: Grant
