Tubtara® blind rivet nuts: 60 years of innovation

Tubtara® blind rivet nuts are especially developed to provide a strong thread in (thin or thick) metal, plastic or composite sheets & profiles.  Installed from only one side, they are very effective in enclosed applications, such as cabinets, profiles, enclosures, pipes etc. 

A proper choice of the right material and coating of the Tubtara® is very important to obtain optimal functionality during the whole life cycle of the application.  Influences can be chemical (in water dissolved elements), abrasive (sand), heat, friction, contact with other metals, corrosive environments etc.

To be complient with European directives Dejond offers a range of coating options on their steel Tubtara's like Zinktop with or without Cobalt (Cr6 -free, 480h red rust) or Ultra 1000 (Cr6 /Ni-free, 1000 h red rust).

For improved corrosion resistance however the Tubtara® range is swiftly progressing towards stainless steel. The Tubtara® in stainless 1.4567 (304/A2) resists corrosion in atmospheric exposure, the stainless 1.4578 (316/A4) version also targets applications exposed to chlorides, salt water and extreme temperatures. Especially for extremely demanding & critical applications like in civil engineering, tunnel infrastructures etc., Dejond recently developed cold formed TUBTARA's in high alloy austenitic stainless steel 1.4571 (316Ti/A5) and 1.4539 (904L/A6). 

To prevent seizure between the (machine-jointed) threaded connections of a stainless bolt in the stainless Tubtara®, a Seal InoxTM topcoat or Gleitmo is recommended.

3D Cad drawings of most stainless steel Tubtara's are downloadable in numerous formats so that you can directly insert them in your product design, in installed or uninstalled condition.
