Furniture screw with countersunk head and eyelet on headrest DIN 604
The din 604 countersunk head screw with headrest is most commonly used in production facilities and less commonly in domestic applications. The physical and technical characteristics of this metal product determine its high value in the assembly of all types of furniture. It is used in combination with washers and nuts with a corresponding internal thread. Furniture screws with a tendril can be manufactured in various variations: from different source alloys, coarse, normal or high precision, with or without a protective coating.
In the regional offices of Eurobolt and in Kyiv, you can buy fasteners wholesale and retail: our price and consistent product quality receive the highest customer reviews.
Installation details and operating features:
A countersunk head and whisker furniture bolt is a strong rod with a specific thread and a round head (with a smooth face). The dimensions of this hardware do not affect the presence of the model’s distinctive tendril: the locking element reliably protects the connected surfaces from unwanted deformation (turning, shifting, unwinding, etc.).
Please note that the din 604 screw is optimal for use with wood (plywood, fiberboard and wood-spring boards). If it becomes necessary to carry out a complex multi-component installation (for example, wood with metal and/or plastic materials), it is important to monitor the placement of the whisker in the wooden parts of the structures.
Features a countersunk head screw and a tendril on the headrest:
simplicity and safety in operation;
environmental friendliness;
high aesthetics and neat appearance of the joints;
resistance to vibration loads.
