Tamper Proof

Tamper-proof screws, also known as security screws, discourage tampering by having a difficult removal method. These fasteners protect projects and the people who use them by securing the screwed-on areas. While they mainly have uses in professional projects, some DIYers may also find them helpful.

Tamper-Proof and Tamper-Resistant Screws

A tamper-proof or tamper-resistant screw offers security through design. It has an unconventional drive that requires a matching bit or driver, making it more difficult to remove them. Since they need a specific bit or driver, potential tamperers can't use commonly available tools to unscrew them. Tamper-proof and tamper-resistant screws have a variety of uses and types.

What Makes a Tamper-Proof Screw Different From a Tamper-Resistant Screw?

Both tamper-proof and tamper-resistant screws follow the same concept, but they have different levels of security. Tamper-resistant screws serve as front-line protection against many types of attacks. However, someone determined to vandalize a tamper-resistant screw can still find ways to remove it. A tamper-proof screw's design makes it physically impossible to remove without using its corresponding tool. The right choice for your project depends on the level of security you need and the other measures you have in place.

Uses for Tamper-Proof Screws

Professional contractors use tamper-proof and tamper-resistant screws for projects involved in many industries. While homeowners can use security screws, as well, they tend to install them in special cases. Projects that use security screws include:

  • Vehicles
  • Computers
  • Signs
  • License plates
  • Fences and rails
  • Bathroom stalls
  • Military equipment

Any project that can benefit from tamper protection can use security screws.

Types of Tamper-Proof Screws

The types of tamper-proof and tamper-resistant screws have different head and thread styles. Security screws come in the following varieties and more:

  • Drilled spanner
  • Torx®
  • Hex socket
  • One-way
  • Tri-wing heads
  • Spanner inserts
  • Shear screws and bolts

Ask a Construction Fasteners and Tools team member for more information about these screws' security methods.
