Abstract
Into a bore which is about to receive a fastener such as a screw, nail or bolt, an adhesive capsule support basket is first placed and mounted at a desired intermediate level. One or more capsule(s) containing adhesive is (are) inserted into the bore and become supported by the basket at the intermediate level. As the fastener is installed, it contacts and bursts the capsule(s), spreading the adhesive at the fastening region. The basket, which is rather flimsy, is destroyed by installation of the fastener, after having performed its role.
