Description of Stainless Machine Drilled Spanner Threads

Stainless steel provides corrosion resistance. Drilled spanner drive resists tampering by requiring a special driver to tighten or loosen the screw using the two holes opposite each other on the screw head. Flat head is cone shaped for use in countersunk holes and has a flat top that fits flush with the mated surface. Plain surface has no finish or coating.

Good for outdoor use. Suitable for electrical boxes.

They fit standard US electrical outlets. I use them to add some security to some of the outer covers of electrical boxes. The price fluctuates greatly. Now it's almost double what I paid. The screws are made of stainless steel and are therefore less prone to rusting than galvanized screws.

Pros
  • Mounting Screws
Cons
  • Ugly Packaging
