6.3.2.4.2 Type values
| Type | Description | 
|---|---|
ANCHORBOLT
 | 
 A special bolt which is anchored into concrete, 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.  | 
CHAIN
 | 
 a series of linked metal rings used for fastening or securing something, or for pulling loads.  | 
COUPLER
 | 
 A part connecting two rod or bars, such as reinforcement bars.  | 
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.  | 
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.  | 
RAILJOINT
 | 
 A mechanical assembly with e.g. fishplates to join two rail ends with optional functions (insulation or expansion capacity).  | 
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.  | 
ROPE
 | 
 a length of thick strong cord made by twisting together strands of hemp, sisal, nylon, or similar material. used primarily for mooring vessels  | 
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.  | 
USERDEFINED
 | 
 User-defined mechanical fastener.  | 
NOTDEFINED
 | 
 Undefined mechanical fastener.  |
