ABSTRACT:
A bolted connector for joining a pair of metal piece parts that exhibits improved stiffness is made by forming a burred aperture on one of the metal piece parts. The piece parts are configured to include bolt apertures with slightly different diameters, the piece part included the burred region comprising the lesser diameter. When the piece parts are joined, the burred region is forced into the second aperture. Once the pieces are joined, a threaded bolt is inserted through the first and second pieces and a nut is threaded onto the bolt shank to contact the underside of the second metal piece part. The burr functions as a physical "stop" within the second aperture and prevents relative motion between the piece parts.
