HOW TO CHOOSE THE RIGHT SECURITY NUT

Is your installation permanent or semi-permanent?

Permanent Installation

The hex head breaks away during installation, leaving a tamper-resistant cone. Best when future removal is not expected.

Semi-Permanent Installation

Tri-Groove Security Nuts

Tamper-resistant, but removable with the correct matching Tri-Groove socket. Best when future maintenance may be needed.
