METHOD OF ENGAGING A BOLT WITH AN APERTURE

摘要

A method of establishing a bolted joint involves forming a flared aperture (14) and inserting a bolt (16) through the aperture. Thereafter, the aperture is compressed such that the flared aperture is flattened and such that the effective dimension of the aperture is reduced and the flattened aperture engages the shaft of the bolt (Fig 3). Desirably, at least a portion of the perimeter of the flattened aperture is urged between adjacent threads of the shaft of the bolt. The underside of the nut (18) does not include a lead-in chamfer.
