The following tables offer a handful of indicative standard values for Tubtara® blind rivet nuts with a round or hexagonal shank and flat head in first grip:
In practice, variations may result from differing setting and environmental conditions. The values mentioned can be used as a reference and optimised by using additional features. We strongly advise customers to perform their own tests in the correct material thickness and specific application.
In addition to the standard inspections during the blind rivet nuts’ production process, the following tests can be done at the customer’s request:
