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. |
