This is a Grade 5 Titanium 6 pack of 14mm head bolts for the rear lower control arms of EF DA EG DC EK chassis.
These work with Beaks bars if no brace is used with that bar. 
Subframe Braces like ASR and F7 work with the kit specifically made longer for these braces. These still will not work with Beaks bars over the subframe braces.
