DIN/ISO standard parts: screws, nuts and washers for industry
Standard parts are the basis of every connection and the invisible heroes in the world of mechanical engineering and construction. They are the essential fasteners found in almost every machine, device and structure. From screws and nuts to washers and bolts. DIN/ISO standard parts can be found everywhere.
What are standard parts?
Standard parts are standardized fasteners such as screws, washers and nuts that are manufactured according to specific norms and standards. These standards, often referred to as ISO DIN standard parts, ensure that the parts are consistent in terms of size, shape, material and quality. This allows engineers, for example, to design and build with confidence, knowing that the parts they are using are reliable and compatible.
What are standard parts used for?
DIN/ISO standard parts are used in a variety of applications. They are essential for the assembly of machinery and equipment, the manufacture of vehicles, and the construction of buildings. Standard parts provide a safe and reliable method of joining components and ensure the structural integrity and function of end products.
