If you’re uncertain about the hex nut dimensions for Pomona Electronics’ Model 3276 and 4513 Banana connectors, here’s a clarification for you.
When reviewing the datasheet, it’s important to note that the hex diameter shown refers to the hex portion of the connector itself, not the hex nut.
The datasheet specifies that the Hex nut for both Model 3276 and Model 4513 banana plugs is a 4-40 Stainless Steel Nut. However, it does not provide the exact hex nut dimensions beyond this standard sizing. Any 4-40 hex nut can be used, if the provided one does not fit your assembly.
