Product information

DIN 981 is a slotted round nut, designed for securing bearings, bushes and other shaft assemblies. It is tightened with a C-shaped spanner and is most often used together with the DIN 5406 lock washer, which protects the connection from loosening. By design this nut has precise threads and a flat bearing surface, which makes a stable, vibration-resistant connection possible. Made from steel or stainless steel (A2, A4). Tip: - DIN 1804 – similar, but with a fine thread, more often used for precise mechanical connections. - DIN 981 – a standard-thread nut, most often used for securing bearings together with DIN 5406.
