Tamper-Resistant Drilled Spanner Nuts
A wide base and large bearing surface make these nuts good for securing large objects. They must be installed and removed with a spanner driver (sold separately). Use them to reduce the risk of unwanted removal for objects in public spaces such as signs, lighting fixtures, and displays. Made from zinc alloy, they're corrosion resistant in wet environments.

Tamper-Resistant Tri-Groove Nuts
Tri-groove nuts are narrower than sloped and drilled spanner nuts to fit in tight spaces. Install with a 3/8" tri-groove socket bit and drive handle (sold separately). Use them to reduce the risk of unwanted removal for objects in public spaces such as signs, lighting fixtures, and displays.
Zinc alloy nuts are lightweight and corrosion resistant in wet environments.

Tamper-Resistant Breakaway Nuts
The most tamper-resistant nuts we offer, these have a hex head that breaks away upon tightening, leaving a non-removable cone. They can be installed using a standard wrench. Use them to reduce the risk of unwanted removal for objects in public spaces such as signs, lighting fixtures, and displays.
Zinc alloy and zinc-plated alloy steel nuts are corrosion resistant in wet environments.
