Customer Service

The Experience Exchange Group EK1, which is composed of all GS bodies recognized under the Product Safety Act for products covered by the Low Voltage Directive, has published a decision on the use of screws to prevent the opening of the housings of non-re-connectable plugs, coupling sockets and multiple sockets (DIN VDE 0620-2-1 (VDE 0620-2-1) January 2016, section 14.1, ProdSG):

The screws’ head shape must be designed to prevent any manual opening using hand tools. Recessed one-way screws that allow positive force transmission only in the closing direction are seen as an acceptable example. In any case, it must be ensured that non-destructive opening is not possible.

Screws that allow a torque in both closing and opening direction are not considered as safety screws in the sense of the standard.

This requirement is included in the specifications for obtaining the GS mark. GS certifications that do not yet meet the above requirements lose their validity.
