Tamper resistant machine screws feature specialized drive types — spanner, pin-in six lobe, one-way, pin-in hex socket, and tri-groove — that require non-standard tools to remove. Available in a full range of thread sizes from #4-40 through 1/2-13, in 18/8 stainless steel, brass, alloy steel, and zinc plated steel. Common applications include public fixtures, electronics enclosures, transit infrastructure, and access panels.
