Drilled-Spanner-Drive Tamper-Resistant Nuts

A wide base and large bearing surface make these nuts good for securing large objects. They must be installed and removed with a nutdriver (sold separately). Use them to reduce the risk of unwanted removal for objects in public spaces such as signs, lighting fixtures, and displays.

Zinc—Made from zinc alloy, they're corrosion resistant in wet environments.
