Pin
The cleat is a special bracket in the building industry, through which forces from a component are transferred to a component that is offset parallel to the original force curve. Brackets of this type are mainly referred to as lugs when building with rod-shaped elements, i.e. in timber and steel construction.
Wooden framework
In the historical half-timbered structure with cantilevered upper floors, lugs are built in to stiffen and transfer loads between the posts and the cantilevered ceiling beams. The connection to the cantilevered ceiling beam is made by a pin , the connection to the stand by an offset when vertical loads are to be transferred. The studs are often provided with carvings, figures or ornaments .
In contrast to the headband or the bow, the clasp is not located in the compartment , but forms a construction element protruding from the wall structure.
There is also the definition that the clasp completely fills the angle and the bend leaves an open triangle. This definition is not tied to the protruding position, but only differentiates the shape of the headband.

Rafter roof
In many rafter roofs , cleats are used to transfer the forces from the rafters into the supports of a concrete ceiling. This makes it possible to use continuous pieces of wood for the roof surface and roof overhang and thus obtain a kink-free roof view as with the purlin roof . In the case of a direct introduction of the forces from the rafter (without cleat), the rafter must end at the support, the roof overhang is then formed by a slide , which results in a lower roof pitch in the lower area and in the roof overhang.
steel construction
In steel construction, cleats can be used to transfer the vertical loads from a beam to a support or to the wall. These consist of small steel plates that are welded to the support or a connecting plate anchored in the wall. The girder or a head plate welded to the end of the girder then rest on the bracket and thus transfer vertical loads to the support or wall without the wall or support having to be interrupted or weakened by openings.

In mechanical engineering, clamping elements in manufacturing technology as well as fastening or stop angles are also referred to as cleats .
