schumag fasteners Germany schumag models schumag prices

schumag fasteners feature internal threaded holes. They are generally flat hexagonal prisms, but can also be flat square prisms or flat cylindrical shapes. Used with bolts, studs, or machine screws to securely connect two parts into a single unit. Nuts operate by self-locking through friction between the nut and bolt. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are taken to ensure reliable nut locking. As an essential component for all manufacturing machinery, they are classified by material into carbon steel, stainless steel, and non-ferrous metals (such as copper).
