Long-lasting outdoor performance - with A4 marine grade stainless steel
A4 stainless steel offers high resistance to corrosion and pitting in saltwater environments, using higher chromium and molybdenum content than ordinary grades.
Keeps fixings rust-free and structurally sound in coastal or exposed settings, reducing maintenance and replacement frequency.
Tamper-resistant installation - thanks to permacone snap-off head
Permacone snap-off design shears the head at installation torque, removing the drive recess and preventing easy removal with standard tools.
Discourages unauthorised removal and helps protect fittings in public areas or other vulnerable locations.
Neat, low-profile finish - with shear-off head design
After tightening, the protruding section breaks away to leave a smooth, low-profile surface that sits flush with the nut body.
Gives a discreet appearance for visible fixings and reduces snag hazards on exposed installations.
