Abstract
A protective helmet having a rigid outer helmet shell, an inner pad assembly formed from a resilient material and threaded fasteners partially embedded in the inner pad assembly and adapted to secure the inner pad assembly into the outer helmet shell. The embedded fastener has a threaded aperture to receive a securement means such as a threaded screw, and a non-circular portion, which protrudes from the inner pad assembly and is inserted in a corresponding mounting hole on the outer helmet shell. The non-circular portion of the fastener prevents rotation of the fastener when the threaded securement means is fastened into the threaded aperture during installation or removal of the inner padding assembly.
