Breakaway nut INOX

I15
.
61

The INOX breakaway nut is a specialized security fastener designed to prevent removal after installation.
Made of high-quality stainless steel, it combines corrosion resistance with mechanical durability.
During tightening, once the specified torque is reached, the hexagonal head breaks off, leaving a smooth conical surface that cannot be gripped with standard tools.

Applications:
Used wherever a permanent and reliable protection against unauthorized disassembly is required:

  • urban infrastructure (traffic signs, lighting),

  • fences and gates,

  • industrial equipment,

  • public devices and outdoor installations.

Benefits:

  • Permanent protection – cannot be removed with standard tools after installation.

  • Corrosion resistance – stainless steel INOX ensures long service life.

  • Easy installation – mounted with a standard wrench until the breakaway head separates.

  • Anti-theft and anti-vandal protection – effective in public and industrial environments.
