Rugged UHF Bolt & Screw RFID Tags

The tag is a rugged and durable tag that is suitable for tracking all kinds of outdoor equipment and resists high temperatures and pressure. It is perfectly suitable for the oil and gas industry, as well as for tracking other outdoor equipment, reading range up to 3m. Vary standard and non-standard bolt models.


RFID bolt and screw tags offer a seamless solution for permanently attaching an RFID Tag to an item or asset.   The RFID screw tag stands out due to its superior chemical resistance and 360-degree reading capability, making it optimal for manufacturing control tasks. With an operational temperature range spanning from -40°C to +150°C, it's suitable for scenarios where a screw-in RFID tag of this design is essential. Its reading range extends up to 3m, although this depends on the reader. Encased in a unique steel alloy and fortified with premium-grade epoxy, this tag boasts a prolonged lifespan, adapting to various applications over the years.   Crafted from hardened steel, the bolt's body ensures extended durability. Presently, in several automotive industries, this screw tag is embedded into a part, typically metal, loaded with necessary data, and later erased and detached. Subsequently, it's reverted to the start of the process for reuse. However, innovative applications are emerging. For instance, a screw tag can be inserted into an apparatus like an oil or gas valve, a cylinder, or even a plate, functioning as a bolt. Once embedded, it serves as a tracking mechanism, especially useful for tasks like field servicing after the equipment is operational.     Key Features:

  • Superior chemical resistance and full-circle reading capability.
  • Enhanced durability thanks to the steel alloy coating and robust epoxy.
  • Versatile use, from manufacturing setups to field servicing applications.
  • Longevity due to the hardened steel body.
