This enumeration defines the different types of mechanical fasteners.

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.
