Torx® Security Screws - Star Drive Security Screws

Star Drive Security Fasteners

Tamper Proof Security Screws and Matching Security Bits

Tamper proof screws, or tamper resistant security screws, are distinguished by having an unconventional drive, making tampering with the screw more difficult, if not impossible without the matching driver. This in turn makes them a more secure option than the run of the mill screw. Tamper proof 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 preparation and processing areas. You will often see security screws used in bathroom stalls, particularly toilet partitions and other public locations. Tamper proof screws in this selection are grade 18-8 or higher stainless steel, which prevents rusting and is corrosion resistant.

Star with pin security drive can only be driven with security bits and are used to prevent tampering and theft. Security screws in this variety are characterized by the 6 lobe, or Torx style with a central pin. The pin grants additional tamper resistance as it prevents conventional screwdrivers and grabbing devices from tampering with the original installation.
