The category of Lock Nut Types encompasses several specialized fastening solutions designed to prevent loosening under vibration and dynamic loads. Among these, the DIN980M stainless steel metal lock nut (M-type) represents a significant engineering advancement. These full-metal, two-piece hexagonal nuts incorporate a unique pre-load torque mechanism that distinguishes them from standard fasteners. The fundamental design principle of these Lock Nut Types involves integrating an additional metal element within the nut’s structure to enhance frictional resistance and maintain clamping force integrity throughout the service life of the assembly.
The operational mechanism of these specific Lock Nut Types relies on their two-piece construction, where an inserted metal element creates increased friction against the bolt threads. This design fundamentally differs from single-piece nuts by providing a more reliable locking action that doesn’t diminish through repeated installation and removal cycles. The engineering behind these Lock Nut Types ensures consistent performance where conventional nuts might fail, particularly in applications involving constant vibration, thermal expansion, or variable mechanical stresses that could compromise joint security.
Material composition significantly enhances the performance characteristics of these Lock Nut Types. Manufactured from 304, 316, or 201 stainless steel, these fasteners offer varying degrees of corrosion resistance and mechanical strength to suit different environmental conditions. The surface treatments,either natural finish or passivation,further improve their durability against corrosive elements. This material selection ensures that these Lock Nut Types maintain their locking properties while withstanding exposure to moisture, chemicals, and other potentially degrading substances.
A key differentiator for these specific Lock Nut Types is their exceptional high-temperature performance. Unlike standard DIN985/982 nylon-insert lock nuts that have temperature limitations, these full-metal variants remain fully functional at temperatures exceeding 150°C. This thermal stability makes these Lock Nut Types particularly valuable for automotive, industrial machinery, and energy applications where elevated operating temperatures would compromise the integrity of non-metallic locking elements.
The DIN980M specification Lock Nut Types provide engineers with reliable fastening solutions for demanding applications where vibration resistance and thermal stability are critical. Their two-piece metal construction, corrosion-resistant materials, and proven high-temperature performance make them superior to conventional locking fasteners in challenging environments. These Lock Nut Types represent an optimal choice for permanent installations requiring maintained clamping force and anti-loosening protection throughout the product lifecycle.
