Drilled Spanner

Drilled Spanner Screws are tamper resistant screws, also known as tamper proof screws, that require a special spanner driver to install. Spanner screws are typically available in Pan, Flat and Truss heads in both steel and stainless steel. Typical sizes are listed below though Apex Fasteners can supply parts in nearly any size to meet your particular application's needs. Drilled Spanner machine screws and drilled spanner sheet metal screws are available. Drilled Spanner drives can also be found on certain tamper resistant nuts. Please see our Drilled Spanner Tools for installation assistance.
