A fluid filter assembly is provided comprising a filter can, a filter cover assembly, and an interior filtering assembly. The filter cover assembly comprises an outer cover plate and an inner mounting plate. The outer cover plate of the filter cover assembly comprises a drawn-down portion that descends toward the interior volume of the fluid filter assembly and exhibits a metallic grain structure that is stretched relative to the metallic grain structure of the inner and outer circumferential mating portions of the outer cover plate. In one embodiment, the inner mounting plate is secured to a backside of the outer cover plate such that, upon rotational engagement of the internal threads of the inner mounting plate with a threaded fluid port, the inner mounting plate rotates with the filter can and the outer cover plate to advance in an axial engagement direction and forcibly urge the outer cover plate in the axial engagement direction from the backside of the outer cover plate. |
