Böllhoff standard 53030 | Nut material: S45C | Zinc-plated | Material insert: stainless steel | Cr(VI) - free | Metric regular thread
Highest security for your threaded connection. U-NUT® nuts are a reliable and proven solution for all applications where the screws play a crucial role in ensuring function and safety, and where it is essential to prevent the preload force from being lost and the connection from falling apart.
The integrated sheet metal spring ensures that the U-NUT® nut maintains a consistent and controlled clamping force on the thread and that a certain amount of preload force always remains in the connection. Even under maximum loads. The geometry is precisely matched to the screw thread so that repeated tightening is possible throughout without any problems. The effectiveness of the U-NUT® is not dependent on a defined, high level of pre-tensioning force, so the nut is well-suited to planned pre-tensioned connections as well as for soft components and assembly with simple tools. U-NUT® will always secure your connection.
Benefits:
• thread clamping for maximum safety
• easy to assemble
• excellent refastening properties
• temperature and UV-stable compared to conventional locknuts with PA ring
Application examples:
• robotics
• motors
• pumps
• elevators
• machining
