For CE Marking compatibility and measures against contamination

Components that prevent screws from falling off from covers and getting lost

NBK has standardized products for fall prevention of parts in the Machine Elements.
Use NBK's Captive Series for food machinery, packaging machinery and chemical manufacturing equipment that require CE Marking compatibility and measures against contamination.

CE Marking

CE Marking (CE Mark) is a mark demonstrating that the manufacturer is in compliance with the EC Directive for products such as machinery and equipment.
Products that are exported or distributed to EC member states must comply with the EC Directive. Therefore, in order to circulate the products in EU member states, CE Marking is required to demonstrate that they comply with the EC Directive.
According to the "EU Machinery Directive Annex 1" of "Machinery Directive (2006/42/EC)" in the EC Directive, screws that secure a protective cover or inspection cover of equipment and devices must not fall out of the cover when it is removed.
