Tamper Proof Screws

tamper proof screwsTamper proof screws are used in assemblies, applications, and industries as a means to deter or prevent vandalism or disassembly where an assembly is publicly accessible. Tamper proof screws are distinguished by an unconventional drive, making tampering with the screw highly difficult, if not impossible without the matching driver.

Available in a wide range of forms, materials, and styles, tamper resistant and tamper proof screws are intended to provide different advantages in the applications and products where they are installed. 

Tamper proof screws are used in a broad range of industries and applications, including: 

  • Aerospace: to avoid intentional or accidental fastener loosening or removal that could compromise the flight-worthiness and safety of aircraft
  • Automotive: to minimize poor handling, safety issues, and excessive noise and vibration caused by loose or absent fasteners
  • Military: tamper proof fasteners are used to prevent vandalism, sabotage, and mission-critical equipment failure
  • Healthcare: tamper proof fasteners ensure that diagnostic and therapeutic equipment is safe, effective, and continues to function properly without risking patient health
  • Retail: tamper proof screws help prevent expensive goods from being damaged or stolen, as well as protect public safety while inside the store
  • Education: Educational institutions use tamper proof screws to discourage theft, vandalism, and inappropriate usage of desks, classroom and office furniture, and electronics
  • Public Safety: Municipalities use tamper proof fasteners to protect property in public places, and to ensure the safety of the general public.

Tamper resistant vs. tamper proof

There’s a common misconception that tamper resistant screws and tamper proof screws are the same thing, however, that is not the case. Tamper resistant fasteners are relatively difficult to remove because they require a relatively uncommon driver to fit the head. Tamper-proof screws are nearly impossible to remove because they require a unique, often custom, tool. 

“Resistant” implies that the fastener is relatively difficult to remove with tools that might be found in the average tool chest, thwarting any casual, opportunistic attacks but offering little protection in cases where someone deliberately intends to remove that particular fastener. “Tamper proof” increases security exponentially because the unique driver is virtually impossible to acquire without having purchased that particular style of fastener and the requisite tool needed to install it.
