HISTORY New Enumeration in IFC4.
| Constant | Description |
|---|---|
| ANCHORBOLT | A special bolt which is anchored into conrete, stone, or brickwork. |
| BOLT | A threaded cylindrical rod that engages with a similarly threaded hole in a nut or any other part to form a fastener. The mechanical fastener often also includes one or more washers and one or more nuts. |
| DOWEL | A cylindrical rod that is driven into holes of the connected pieces. |
| NAIL | A thin pointed piece of metal that is hammered into materials as a fastener. |
| NAILPLATE | A piece of sheet metal with punched points that overlaps the connected pieces and is pressed into their material. |
| RIVET | A fastening part having a head at one end and the other end being hammered flat after being passed through holes in the pieces that are fastened together. |
| SCREW | A fastener with a tapered threaded shank and a slotted head. |
| SHEARCONNECTOR | A ring connector that is accepted by ring keyways in the connected pieces; or a toothed circular or square connector that is pressed into the connected pieces. |
| STAPLE | A doubly pointed piece of metal that is hammered into materials as a fastener. |
| STUDSHEARCONNECTOR | Stud shear connectors are cylindrical fastening parts with a head on one side. On the other side they are welded on steel members for the use in composite steel and concrete structures. |
| COUPLER | A part connecting two rod or bars, such as reinforcement bars. |
| RAILJOINT | A mechanical assembly with e.g. fishplates to join two rail ends with optional functions (insulation or expansion capacity). |
| RAILFASTENING | An assembly of components which secures a rail to the supporting structure and retains it in the required position whilst permitting any necessary vertical, lateral and longitudinal movement. Note: definition from EN 13481-1. |
| CHAIN | a series of linked metal rings used for fastening or securing something, or for pulling loads. |
| ROPE | a length of thick strong cord made by twisting together strands of hemp, sisal, nylon, or similar material. used primarily for mooring vessels |
| USERDEFINED | User-defined mechanical fastener. |
| NOTDEFINED | Undefined mechanical fastener. |
