The Iron lock nut (DIN980) is a high performance anti-tension firmware in accordance with the German industry standard DIN980, designed to solve the problem of loosening of bolt connections under mechanical vibration, shock or dynamic load environments. Its unique construction achieves reliable anti-loosening effect through built-in preset iron (locking gasket), which is suitable for industrial scenarios with high safety and stability
requirements.
Core Features: 1. anti-loosening principle : The bottom of the nut is integrated with a specially designed metal lock plate, which produces elastic deformation with the bolt thread during tightening, forming a continuous normal pressure, and effectively cancelling the relative sliding of the thread pair caused by vibration.
2. High strength material : The use of high-quality carbon steel, stainless steel (such as 304/316) or surface galvanized treatment, with high tensile strength and corrosion resistance, to meet different environmental requirements (temperature range: -50ºC to +300ºC).
3. Standardized design : strictly follow DIN980 standard, accurate size, seamless fit with standard bolts, strong adaptability, easy to replace traditional nuts.
4. maintenance-free use : a tightening can maintain the pre-tightening force for a long time, without repeated tightening, reducing equipment maintenance costs.
Application field:
- Rail transit (rail fasteners, vehicle chassis)
- Heavy machinery (engineering equipment, mining machinery)
- Aerospace, automotive manufacturing and other high vibration scenarios
- Power equipment, bridge structures and other critical connections requiring long-term stability
Advantage comparison:
Compared with nylon insert lock nuts, iron sheet design has no plastic aging risk and better high temperature resistance. Compared to the double nut structure, the installation is more convenient and saves space, significantly improving the assembly efficiency.
Technical parameters:
- Locking grade: pass DIN65151 vibration test standard
- Specification range: M5-M36 (can be customized according to demand)
- Surface treatment: galvanized, dacromet, hot dip zinc, etc
The iron lock nut DIN980 is the ideal choice for high strength connections due to its excellent lock resistance and industrial durability, helping equipment operate safely and reducing the risk of unplanned downtime!
