Spanner (Snake Eye) Pan Head Sheet Metal Screw

18-8 Stainless Steel Tamper Resistant Screws

Tamper proof security sheet metal screws Spanner pan Head, also known as a Snake Eye drive. These security screws are used for securing materials from being tampered with, such as gutters, license plates, grills in jails, schools, boats and cars. They are also used in food prep and processing areas. You will often see security screws used in bathroom stalls and other public locations.

18/8 or 18-8 Stainless steel is used primarily for long lasting applications, due to its corrosion-resistant nature and durability. Scratching or burring the metal will not create surface rust as the corrosion resistance exists within the metal itself. Sheet metal screws have sharp cutting threads that cut into sheet metal, plastic or wood. Spanner Sheet Metal Screw shanks are threaded up to the head or to the undercut. Sheet metal screws make excellent fasteners for attaching metal hardware to wood because the fully threaded shank provides good retention in wood. Security screws in this selection feature a pan head with a snake eye drive.
