What design feature of the gland nut enhances its ability to shed liquids?

The design feature that enhances the gland nut's ability to shed liquids is the rounded corners. Rounded corners play a significant role in minimizing fluid retention. This shape allows liquids to flow off more easily, reducing the chances of capillary action which can happen at sharper angles or edges. In contrast, flat edges and sharp edges are more likely to trap fluids, creating areas where liquids can accumulate. A rough texture may also not be as effective at shedding liquid because it can create small pockets for fluid to settle in rather than allowing it to flow away. Rounded corners, therefore, promote a smoother surface for liquid drainage, making them an ideal choice for design features aimed at minimizing liquid retention.
