Parts Desk Insights
Best use case: This nut is most commonly needed during engine and sterndrive reassembly where fine-thread fasteners are specified — particularly in locations subject to vibration, where a fine thread provides better resistance to loosening than a coarse-thread equivalent. Always order by part number from the diagram; fine-thread and coarse-thread nuts look identical on the shelf but are not interchangeable. If you’re doing a full hardware refresh, pick up a few extras — at this price point it’s not worth a second trip.
