The bolts should be tightened to "Snug Tight" in accordance with AISC recommendations.
The bracing end connection has been manufactured to suit the connection plate sizes shown in the Dimensional Information. (One plate size larger and one plate size lower may be used).
The connection plates need to be specifically designed by an engineer.
We suggest you contact your preferred coating supplier for specification relating to the specific environment of the application. We can provide a specification from our coating supplier if required. Please get in touch if you would like more information.
No, a standard nut or double should not be used to replace a nyloc nut. The nyloc nut is used to prevent the nut coming loose during dynamic loading and is a critical part of the system.
The bars are micro-alloyed with a rolled thread. The nuts and connectors have a machined thread.
Standard design values as specified in AS4100 are considered appropriate for the DonoBrace® system. Although the material used in the brace sits outside of AS4100 standard specification for seismic-resisting elements, the behaviour of the material and brace system has been reviewed and tested for its equivalent performance.
