Standard screws: characteristics and specifications
Standard screws, also known as metric thread screws, are characterised by having a standardised thread pitch according to different systems. One of the main characteristics of this type of screws is that they offer a high resistance at the moment of application and allow the use of washer and nut in order to reinforce the grip. They are mainly used in mechanical joints with the aim of creating a powerful and durable fastening. The variety in metrics, heads and lengths that you will find in our catalogue guarantees you flexibility in the assembly to carry out all your projects without complications.

What does DIN mean in fasteners and ISO?
The DIN standard (from the German Institute for Standardisation) in the field of fasteners certifies the quality of materials and defines a standard of measurements and specifications, so that they can be used worldwide. The use of standardised DIN screws therefore results in an optimum and efficient connection at all levels. The ISO standard fulfils the same function as DIN, but is defined by the International Organization for Standardization.
