<p>Case 3758 LOAD DISTRIBUTING WASHER FOR PLASTIC MEMBER A specially designed washer for attaching a plastic member to a metal substrate. The washer has a generally polygonal configuration with a metal-substrate-engaging member which projects through the plastic from an off-center location. This member provides some dissipation of the clamp load through a metal-to-metal contact path through the plastic and also acts as a pivot point for the washer to transfer another component outwardly from the aperture in the plastic and distribute it over a wide surface area to reduce plastic creep and eliminate loosening of the joint. A crowning of the washer body dissipates additional clamp loading from the resulting spring forces.</p> |
