ABSTRACT:
A protective helmet comprising an outer helmet shell of rigid material and having a fastener mounted into the outer helmet shell. The fastener comprises a rivet and a washer. More particularly, the rivet includes a flanged head portion at a first end of the rivet, a post part at a second end of the rivet, and a section having an obround cross-sectional shape intermediate the flanged head portion and the post part. The post part can be flattened against the washer to form a compound flanged structure abutting against the helmet shell. The fastener further comprises an elongated aperture extending longitudinally from the post part to the flanged head portion. The aperture is threaded to accept a screw-type securing means that can be used to retain accessories such as a face shield onto the protective helmet. The obround section of the fastener locks with the helmet shell so as to prevent the fastener from turning when the screw-type securing means is engaged therein.
