A cavity is formed in the upper side at the aperture that defines an opening in the upper side, with the opening defined by the cavity being larger than an opening defined by the aperture whereby the cavity includes a seat that is disposed about the aperture and is recessed from the upper side. The fastener further includes one of either a flange or a secondary washer at the head, with the shaft of the fastener configured for insertion into the aperture with the flange or secondary washer recessed within the cavity.
