DEVICES FOR FASTENING OR SECURING CONSTRUCTIONAL ELEMENTS OR MACHINE PARTS TOGETHER, e.g. NAILS, BOLTS, CIRCLIPS, CLAMPS, CLIPS, WEDGES, JOINTS OR JOINTING
Definition statement
This subclass/group covers:

Fastening elements for constructional parts per se, such as: clamps, clips, dowels, nails, staples, bolts without screw thread, pins, rivets, circlips, self-cutting screws, screws and bolts with thread, nuts, lock-nuts, threaded inserts, washers, hooks, suction cups

The connection of constructional elements such as key-type connections, shrinkage connections, joining of sheets and plates, connections of rods or tubes mutually or to flat surfaces at an angle, connections of constructional elements by sticking or pressing them together, joining of furniture, connections of constructional elements by a part of one element entering a hole in the other

The fastening elements or connection of elements in this group can be employed in multiple technical application fields. However, the focus is on the fastening element or the connection of elements itself.

Relationship between large subject matter areas

Fastening elements in this subclass are caracterised by their constructional or functional aspects. Fastening elements which are specially adapted or designed for a specific technical application are generally rather classified in the specific technical application field.

Special rules of classification within this subclass

As a general rule, multiple classifications can be attributed to one document. Symbols for inventive information and additional information are attributed to the corresponding fields.

If there are interesting functional features of an invention specially adapted for an application, at least a symbol for additional information in F16B should be given to this document.

Many documents describe a fastening element itself and a connection comprising the fastening element. If the focus of such a document lies e.g. on the fastening element itself, a symbol for invention information should be given for the fastening element and a further symbol for additional information should be given for the connection and vice versa according the focus.

Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
