The Tamperproof Screw Myth

Tamperproof screws are not as tamper proof as people think. Most styles are vandal proof only. The reason is that security screw bits have become easily obtainable, and there are tens-of-thousands in circulation.

Security screws have been in existence for 50 years and most are without patent protection. "Tamperproof" bits are being manufactured, imported, and widely distributed, without restraint. The following are sources:

The 20000 outlets for tamperproof bits include bolt and nut distributors, True Value® hardware stores, NAPA® stores, independent tool companies and the internet. There are over 200000 catalogues in circulation (McMaster-Carr, Grainger, Sears, and Stanley) marketing security bits. One can easily buy tamper proof bits. With these bits so easily obtainable, it has made Torx®-pin, Hex-pin, Phillips®-pin, Spanner, Triwing®, Tri-Groove, and One-Way screws "vandal proof" only. "Tamperproof screws" is a myth.

Bryce Fastener has come up with a solution to this problem by designing a new line of security screws that truly are tamper proof:

  • KEY-REX™ is a "lock" keyway in the screw head (LOCK-N-KEY™). The keyway is private and access-controlled by the customer.
  • Penta-plus™ is a private access tamperproof screw, designed and access-controlled by Bryce.
  • Penta Nut is a private access tamperproof nut, patented and access-controlled by Bryce.

KEY-REX™ is more than a tamper proof screw. It is the next paradigm in high security screws called "LOCK-N-KEY™". KEY-REX™ has the features and benefits of a lock and key. It’s 16 million secret key code variations keep it exclusive and secure. We encourage users of "vandal-proof screws" to switch to KEY-REX™.

We make the following assessment of the security value (1-10 scale) of "tamperproof screws":

KEY-REX™ and Spin-lok™ are the most secure, making them "high security screws". Penta-Plus™ is the best of the "tamperproof screw" styles. If you need security, we recommend these. The other screw styles are tamper-resistant or vandal proof only. Assess your security risk, before using these. Bryce Fastener distributes the following vandal proof screws: Hex-pin and Tam-6lobe™(the same as Torx®-pin).

The Hidden Costs and Your Loss Potential
Consider the cost of the "loss of the valuable product or the cost of a lawsuit" when picking your fastener. Some real life examples:

  • A school of higher learning had some students remove the tamperresistant security screws and drop a 40 lb rock 10 floors onto a new Mercedes, demolishing the automobile.The cost was $50,000.
  • A major university had expensive electronics (secured with Torx-pin tamper-resistant screws) stolen from a classroom.The cost was $30,000.
  • An art museum is sending its Picasso paintings on tour, partially secured with hex-pin security screws.This bit can be purchased at any True Value hardware store. Do you think it is a good idea?
  • A major electronics company does not want anyone adjusting a control mechanism for a motor (there are large liabilities if it does not perform). They chose KEYED-LOK® to avoid tampering.To date, no tampering has occurred.
  • Projection equipment costs $7,000.00, but is stolen when it is secured with"tamper-resistant screws."
  • Criminals have security bits smuggled into jails allowing them to hide drugs behind wall plates and even escape.
  • All of these examples have "hidden costs" that far exceed the price of tamperproof screws like Keyed-Rex™ and Penta-Plus™.

"Tamper Proof" fasteners are becoming obsolete because bits are so easy to reproduce. With bits becoming more accessible, so are your products and users need to reassess their liability and loss potential. Take a moment to fill out our Loss Potential Liability form to see if you are at risk from:

  • Loss of goods diminished Tampering /vandalism costs diminished
  • Information/ trade secrets secure
  • Customer satisfaction/ Market share increased
  • Product’s/Engineer’s security reputation.
  • Avoidance of legal liability
  • Terrorism averted
  • National Security improved

When choosing your security screw, it is important to realize that the security bits are being imported and sold at an alarming rate.Theft-resistant and tamper-resistant screws will only stop the naive. Can you afford the cost? Choosing a tamperproof product such as Key-Rex™ or Penta-Plus™, will protect your property — and your investment.
