DEVICES FOR FASTENING OR SECURING CONSTRUCTIONAL ELEMENTS OR MACHINE PARTS TOGETHER, e.g. NAILS, BOLTS, CIRCLIPS, CLAMPS, CLIPS OR WEDGES

**Definition:** This place 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.

**Limiting references (this place does not cover):** - Couplings transmitting rotation -> F16D

**Glossary:** - Connections using screw-thread elements: the connection is established by the screw-thread element - A screw acts on another element in order to establish a clamped connection: a connection using clamps
