We offer both Standard and European threaded cleaning tools. The thread types are not interchangeable. You cannot use a EURO threaded handle with a Standard threaded push broom head. When determining what handle is needed for the cleaning tool head you are purchasing, we indicate on the product page which type of handle is needed to work with the cleaning tool head. All European threaded items have "EURO" as part of the product name. If the product head being purchased has the word "EURO" in the name, then you will want a handle which also has the word "EURO" in it. Example: 16 in UST Push Broom Soft - EURO goes with 51" Fiberglass Handle - EURO.
