Key-Rex

Product Image

KEY-REX is not just a tamperproof, vandal-proof, tamper-resistant screw. Key-Rex fasteners are the world's most secure, tamper-proof screws and bolts on the market. Every set of Key-Rex screws and bolts are custom "keyed" for the client. Only the client has the bits to fit their custom set which are designed to be nearly impossible to remove without the bit.

Key-Rex shapes are created using an encryption process that builds a shape out of millions of variables and defines a unique code for each part. Customers pay for a one-time key code tool and licensing agreement.

Key-Rex Screw - tamperproof, vandal-proof & tamper-resistant.

Key-Rex®:

  • Is the only high-security fastener of its kind
  • Requires a perfectly manufactured companion key/bit to remove
  • The keyway is licensed, private, and unique for each user for total "lock" security
  • Repels all other security bit tips and common tools
  • Can be power driven for speed and torque
  • Is rust-proof, stainless steel or 4037CrV steel with 150,000 psi
  • Is the least expensive "lock" on the market
  • When manufactured with the optional Raptor™ claw grip, it handles 20% more torque and provides more grip than any other security bolts and screws on the market.

Key-Rex™ Micro Self-Tapping Screws

KEY-REX™ Custom High Security Screws Button (Flat) Self Tapping Screws, 18-8 Stainless Steel

Micro self-tapping metal screws are ideally suited for tamper proof plastic applications. Standard micro selftapping screws usually come in a blunt point style and sometimes in a plastics thread. Key-Rex® however, is available in stainless or alloy steel for toughness and designed to meet the requirements of your specific application. Since each screw is individualized, the head diameter is also often customized to add extra security. With the low minimums, and custom features, Key-Rex® Micro self tapping screws are the most economical, high security, tamperproof screws in the industry.

Key-Rex™ Micro Machine Screws

KEY-REX™ Custom High Security Screws Button (Flat) Self-Tapping Screws, 18-8 Stainless Steel

Micro machine screws are tamperproof screws that are very small in diameter and ideal for small instruments or electronics that require high security. KEY-REX® screws are manufactured out of stainless or alloy steel for the toughness required in high security applications. Since each KEY-REX® socket is custom designed, it is easy to custom other features such as head diameter and threads to fulfill specific high security needs. Micro tamper-resistant screws (in any style) are not usually stock items and must be special ordered. KEY-REX® screws do not require big minimums for special orders, and thus are the most economical as well as the most secure tamperproof fasteners available.
