Detailed article description for DIN 985 hexagon nuts, polyamide clamping part, low form (=standard)
DIN 985 hexagon nuts with polyamide clamping part, low form are hexagon nuts with metric standard thread (M) and an additional locking feature to prevent accidental loosening. Lock nuts are also called stop nuts. These lock nuts have a polyamide clamping part (the color of the ring is usually blue, white or green). Unlike solid metal lock nuts, nuts with a polyamide clamping part are cheaper, but are less resistant to high temperatures. With small diameters, it is possible to unscrew them by hand until the plastic part takes effect. From M8, however, this is usually no longer possible - a socket wrench or a socket must be used.
Low or high form of lock nuts?
The low form (DIN 985) is the standard. It has a comparable height to a hexagon nut. The high form (DIN 982), on the other hand, is significantly higher and is usually only used for special requirements.
Function and structure of DIN 985 hexagon nuts with polyamide clamping part, low form
When manufacturing a lock nut, a ring-shaped elevation is attached, on the inside of which a ring is located, which is attached in a groove. When the lock nut is tightened onto the screw thread, the thread deforms and meshes with the locking ring - the locking effect is created by the frictional connection that occurs.
When do I use DIN 985 hexagon nuts with polyamide clamping part, low form?
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, lock nuts are used to protect components against vibration when driving.
How do I install DIN 985 hexagon nuts with polyamide clamping part, low form?
It is not possible to install lock nuts safely by hand and without tools. You can screw the nuts "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 clearly noticeable resistance. Tools are also required to loosen the connection. Please note: unlike normal nuts, lock nuts cannot (!) be reused after disassembly. The securing plastic or metal insert is destroyed by disassembly. The ring cannot be replaced either. Lock nuts should only be screwed 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 DIN 985 hexagon nuts with polyamide clamping part, low form
We offer lock nuts in both the low form (DIN 985) and high form (DIN 985, DIN 6924). They are available with metric standard thread or fine thread and in all common materials and 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.
