Function and structure of lock nuts
When manufacturing a lock nut, a ring-shaped elevation is attached, on the inside of which a ring made of plastic or solid metal sits, which is attached in a groove. When the lock nut is tightened onto the screw thread, the thread deforms and interlocks with the locking ring - the locking effect is created by the resulting frictional connection.
When do I use lock nuts?
Lock nuts are always useful when a screw connection should not come loose or should only come loose with difficulty, or when the part is safety-critical. Examples can be found in mechanical engineering, overhead installation on ceilings, in wood construction (e.g. carports) and in the automotive sector. There, components are secured against vibration when driving using lock nuts.
How do I install lock nuts?
Lock nuts cannot be installed securely by hand and without tools. You can screw the nuts on "hand-tight", but you need a wrench or socket wrench with the right wrench size to tighten them securely. This tightens the lock nut with noticeable resistance. Tools are also required to loosen the connection. Please note: unlike normal nuts, lock nuts cannot (!) be reused after they have been dismantled. The securing plastic or metal insert is destroyed by dismantling. The ring cannot be replaced either.
You should only screw lock nuts onto a thread until the thread of the bolt protrudes a few millimeters beyond the nut. If you screw them onto a bolt too far, there is a risk that the threads will "seize".
Materials and designs of lock nuts
We offer lock nuts in both the low form (DIN 985) and high form (DIN 982, DIN 6924). They are available with metric standard thread or fine thread and in all common materials as well as with corrosion protection for outdoor use such as stainless steel A2, A4, galvanized steel, brass or yellow galvanized steel. Locking cap nuts also have a visually appealing shape. We also offer assortments with lock nuts. When processing solid metal lock nuts, light lubrication prevents the two metals from "eating".
