Abstract
The invention relates to a combination of a screw member comprising a screw head, a threaded portion and a shank portion which is arranged between the screw head and the threaded portion and has an external diameter that is smaller than the external diameter of the threaded portion, a washer incorporating a passage opening for the screw member and a sleeve the internal diameter of which is greater than the external diameter of the threaded portion of the screw member, whereby said combination is producible in a simple manner but it is nevertheless ensured that the sleeve and the washer are held securely on the screw member.
Claims15
A combination of a screw member comprising a screw head, a threaded portion and a shank portion which is arranged between the screw head and the threaded portion and has an external diameter that is smaller than the external diameter of the threaded portion, a slot-free washer incorporating a passage opening for the screw member and a sleeve the internal diameter of which is greater than the external diameter of the threaded portion of the screw member,
- wherein
- the passage opening in the washer comprises a first region having a diameter which is greater than the external diameter of the shank portion of the screw member and is smaller than the external diameter of the threaded portion of the screw member, and a second region having a diameter which is greater than the external diameter of the threaded portion of the screw member, and wherein
- the sleeve and the washer are connected to one another in such a manner that the sleeve and the washer are held captive on the screw member.
A method of making a combination comprising a screw member comprising a screw head, a threaded portion and a shank portion which is arranged between the screw head and the threaded portion and has an external diameter that is smaller than the external diameter of the threaded portion,
- a washer incorporating a passage opening for the screw member and a sleeve the internal diameter of which is greater than the external diameter of the threaded portion of the screw member,
- comprising the following method steps:
- providing a slot-free washer incorporating a passage opening which includes a first region having a diameter that is greater than the external diameter of the shank portion of the screw member and is smaller than the external diameter of the threaded portion of the screw member, and a second region having a diameter which is greater than the external diameter of the threaded portion of the screw member;
- inserting the screw member into the passage opening in the washer in such a manner that the threaded portion of the screw member moves through the second region of the passage opening in the washer until the shank portion of the screw member extends through the passage opening;
- transferring the shank portion of the screw member from the second region of the passage opening in the washer into the first region of the passage opening in the washer;
- inserting the screw member into the sleeve;
- connecting the sleeve to the washer in such a manner that the sleeve and the washer are held captive on the screw member.
