IstLock®
Locking Nuts - Award Winning bolt locking system!
IstLock is our own patented technology that redefines how bolted joints are secured. By using a unique retaining ring principle, IstLock prevents preload loss and ensures reliable performance under vibration, dynamic stress, or extreme operating conditions. Unlike conventional solutions, it offers damage-free installation, unlimited reusability, and full recyclability.
Tested according to the Junker vibration test, IstLock demonstrated exceptional stability – maintaining preload above the critical 20% safety threshold, where conventional nylon insert nuts, spring washers, and standard nuts fail. The locking ring automatically returns to its original position after disassembly, making the system ready for repeated use without loss of performance. Depending on the application, the locking ring can be produced from engineering plastic (up to 140 °C) or soft copper (over 1000 °C), ensuring reliability even under extreme thermal conditions.
Yes, Ist Lock can make it happen!
IstLock technology provides a unique opportunity for engineers and manufacturers to:
Increase the safety and reliability of their assemblies
Reduce maintenance and downtime costs
Improve sustainability through reusability and recyclability
Apply one universal solution across diverse industries and materials
With its virtually endless lifetime and repeatable performance, IstLock sets a new global standard for secure and sustainable bolted joints.
FAQ
1. How does IstLock work and how is it different from conventional solutions?
IstLock uses a patented retaining ring principle that ensures bolted joints maintain their preload even under vibration, dynamic stress, or extreme conditions. Unlike conventional solutions, it allows damage-free installation and removal, is fully reusable, and completely recyclable..
2. Is IstLock compatible with different materials and fasteners?
Yes, IstLock is universally applicable to all types of materials and standard bolts. Its flexible retaining ring design adapts to different sizes and surfaces, providing high reliability and long-lasting joint performance.
3. How long does IstLock last, and can it be reused?
IstLock has an almost unlimited lifespan and is designed for repeated use without losing functionality. The retaining ring maintains its properties through multiple assembly and disassembly cycles, without damaging bolts or contact surfaces.
