1. Types and Meaning of Fastening Joints (Detachable Joints)

Fastening joints (detachable joints) are made between two or more parts and serve to join or fasten components or assemblies in devices/appliances and plants/installations.

Features of detachable joints are:

- The joint can be detached at any time.
- The joining elements are not destroyed.
- The joining elements can be re-used.

There are two groups of detachable joints.

Detachable joints

form-closed (positive) joints:

force-closed (non-positive) joints:

screw-type joints (screw connectors)

keyed joints

spring-type joints

clamped joints

pin-type joints


plug-type joints (plug-and-socket connectors)


Detachable joints permit easy mounting, dismantling and repair of devices, appliances and installations. For making electrical joints, screw-type joints (screw connectors) and plug-type joints (plug-and-socket connectors) are used.
